- Phillips head screwdriver
- Wire Stripper
Materials Required
- 2, #6 x 1” Wood Screws
- 18 AWG LVT Solid Wire (Low Voltage Connections)
- Optional Adapter Plate 007 (for installation on 2” x 4” gang box)
Installation Location ————————————————
Choose the placement of the thermostats early in the construction process to enable proper wiring during rough-in.
Consider the following:
- Interior Wall.
- Keep dry. Avoid potential leakage onto the control.
- Relative Humidity max 80% up to 88°F (31°C) decreasing linearly to 50% RH at 104°F (40°C). Non-condensing environment.
- No exposure to extreme temperatures beyond 36-122°F (2-50°C).
- No draft, direct sun, or other cause for inaccurate temperature readings.
- Away from equipment, appliances, or other sources of electrical interference.
- Easy access for wiring, viewing, and adjusting the display screen.
- Approximately 5 feet (1.5 m) off the finished floor.
- The maximum length of wire is 1000 feet (300 m).
- Strip wire to 3/8” (10 mm) for all terminal connections.
- Use standard 18 AWG wire for the tN2 connections.
Removing The Thermostat Base
To remove the thermostat base:
- Place a small slot screwdriver or similar tool into the slot located on the top of the thermostat.
- While pushing down against the plastic tab, pull the thermostat away from the thermostat’s base.
Mounting The Thermostat Base
If a single gang switch box is used, an Adaptor Plate 007 is required to mount the thermostat to the box.
- Fasten the base of the thermostat to the adaptor plate.
- Feed the wiring through the openings in the back of the adaptor plate and thermostat.
- Use the upper and lower screw holes to fasten the adaptor plate to the box.
If a switch box was not used, mount the thermostat directly to the wall.
- Feed the wiring through the openings in the back of the thermostat.
- Use screws in the screw holes to fasten the thermostat to the wall. At least one of the screws should enter a wall stud or similar rigid material.
Thermostat Wiring
The thermostat operates a single heating system zone together with a cooling system and fan.
Power and communication are provided to the thermostat by connecting the tN2 terminals on the thermostat to the tN2 terminals on a tN2 Wiring Center, House Control, Zone Manager or Expansion Module. tN2 terminals are not polarity sensitive. Connect the Rc, Y and G terminals on the thermostat to the R, Y and G terminals on the cooling equipment.
tekmarNet® communication allows for cooling operation from rooms where only 2 conductor wire is available. This requires a Zone Manager 334 or Zone Expansion Module 324 directly wired to the cooling equipment. Power and communication are provided to the 530 thermostat from tN2 terminals on the 334 or 324.
Testing the Thermostat Wiring
Testing the Power
If the thermostat display turns on, this indicates that the thermostat is operating correctly and there are no electrical issues. In the event that the display is off, or the display is cycling on and off:
- Remove the tN2 wires from the thermostat.
- Use an electrical meter to measure DC voltage between the tN2 terminals.
If the DC voltage is 0 V (dc) for 20 seconds, then there is an open or short circuit in the tN2 wires.
If the DC voltage is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5 seconds, this indicates the wiring is correct. - Connect the thermostat to the tN2 wires connected to a zone on a House Control, Wiring Center, or Zone Manager.
- If the thermostat display is off, or is cycling on and off, move the thermostat to the next available zone on the House Control, Wiring Center, or Zone Manager.
If the thermostat display remains permanently on, there may be a fault with the previously tried zone on the House Control, Wiring Center, or Zone Manager. If the thermostat display continues to be off, or is cycling on and off, there may be a fault on the thermostat.
If a fault is suspected, contact your tekmar sales representative for assistance.
Testing the Heat Zone Output
- Press the Mode button to set the mode to Heat.
- Press the
button and set the heating temperature above the current room temperature. Make sure the display does not show “WWSD”. - When the H1 symbol appears on the display, use an electrical meter to check for voltage on the House Control, Wiring Center, or Zone Manager relay. The voltage is 24 V (ac) for zone valves, and 120 V (ac) for zone pumps when operating correctly.
Testing the Cooling Contact
- Press the Mode button to set the mode to Cool.
- Press
the button and set the cooling temperature below the current room temperature. - When the C1 symbol appears on the display, use an electrical meter to check for continuity on the Rc and Y terminals. If continuity is present, the relay is operating correctly. If continuity is not present, the thermostat has malfunctioned.
Testing the Fan Contact
- Press the Fan button to set the Fan to On.
- When the Fan symbol appears, use an electrical meter to check for continuity on the Rc and G terminals. If continuity is present, the relay is operating correctly.
If continuity is not present, the thermostat has malfunctioned.
Mounting the Thermostat
To place the thermostat back on the mounting base:
- Place thermostat bottom tabs on matching mounting base notches.
- Pivot top of the thermostat towards wall, ensuring wires clear obstructions.
- The top clasp makes a clicking sound when properly closed.

Sequence of Operation
Heating Operation
The thermostat operates the heating system to maintain the Set Room Heat temperature. The H1 symbol is shown on the display when the thermostat is heating. The heat can cycle on and off within +/- 1.5°F (1°C) of the Set Room Heat temperature.
- Freeze Protection —————————————————-
The thermostat operates the heat whenever the room temperature falls below 40°F (4.5°C), regardless of the thermostat mode. - Heat Terminal Unit —————————————————
When the thermostat is connected to a tekmarNet® reset control, the heat source can be either hydronic or non-hydronic.
When the Heat Terminal is set to Hydronic, the thermostat uses indoor temperature feedback to fine tune the water temperature and also synchronizes the start of a heating cycle so that all thermostats start heating at the same time. This reduces cycling on the boiler.
When the Heat Terminal is set to Other, the thermostat does not use indoor temperature feedback. This allows the thermostat to operate non-hydronic heating systems (example: furnace, electric baseboard, or electric fan coil), while remaining connected to the tekmarNet® system. - Exercising ———————————————————-
When connected to a tekmarNet® reset control, and the heating terminal unit is set to hydronic, the thermostat exercises the heat relay for 10 seconds every 3 days. Exercising helps prevent zone valves or zone pumps from failing due to precipitate buildup. During exercising, the thermostat shows “TEST” on the display. - Flushing ————————————————————
The flushing feature is for open-loop systems that use a domestic hot water tank as a heat source. Flushing ensures that fresh potable water is circulated through the system once each day. If the thermostat is connected to a tekmarNet® reset control with the Flushing feature turned on, the thermostat display will display the “FLUSH” icon for the duration of the flushing operation. - Hydronic System Supply Pump —————————————
When connected to a tekmarNet® system control, the thermostat’s Heat Supply Pump setting affects how the primary pump or mix pump on the system control operates. When connected to the boiler bus, the boiler system or primary pump is operated. When connected to the mix bus, the mix system pump is operated. If the thermostat operates a motorized or thermal motor zone valve, the Heat Supply Pump setting should be set to On.
If the thermostat operates a thermal motor (wax actuator) zone valve, set the Heat Supply Pump Delay setting to On. This provides a three minute delay to allow the zone valve to open before the primary or mix pump is turned on.
In special applications with multiple zoning manifolds, the Heat Supply Pump setting can be set to Off. This allows a Zone Group Pump located on the Zone Manager, or Wiring Center to operate the pump for the manifold. - DHW Tank Priority —————————————————
When a tekmarNet® reset control is heating an indirect Domestic Hot Water (DHW) tank, the thermostat may shut off the heating zones to allow the DHW tank to recover quickly. This is determined by the DHW priority of the tekmarNet® reset control. - Warm Weather Shut Down ——————————————–
When the outdoor air temperature exceeds the Warm Weather Shut Down (WWSD) setting on the tekmarNet® reset control, the heating system is shut off.
Cooling Operation
The thermostat operates the cooling system to maintain the Set Room Cool temperature. The C1 symbol is shown on the display when the thermostat is cooling. The cooling can cycle on and off within +/- 1.5°F (1°C) of the Set Room Cool temperature.
The cooling system has a fixed minimum on time of 2 minutes and a minimum off time of 5 minutes in order to prevent cooling equipment short cycling.
- Air Groups
In order to prevent heating and cooling at the same time, this thermostat can operate together with other thermostats on a tekmarNet® system to form an air group. There can be up to 16 different air groups on the same HVAC system. When this thermostat is set as the Air Group master, it operates the cooling equipment for the group. Other thermostats can be set to become members of the same air group. When the cooling is turned on, all air group member thermostats ensure the heating is off. When operating as an air group, the air temperature readings of all the air group member thermostats are displayed on the master as an average. The air group average temperature is shown as the “Room” temperature while the mode is set to Cool, or the mode is set to Auto and the thermostat is allowing cooling operation. In all other modes, the air group master thermostat measures and displays the built-in “local” temperature sensor measurement.
Fluctuations in the displayed “Room” temperature may occur during automatic mode switch over when the display changes from using the local temperature for heating to using the air group average temperature for cooling.
- Hydronic Cooling —————————————————-
The thermostat has the option to support hydronic cooling using a fan coil or a chilled beam when connected to a heat pump or chiller tekmarNet® system control.
When operating a chilled beam or a fan coil that uses chilled water for cooling but does not use hot water for heating, then the Cool Terminal Type should be set to Coil. The thermostat activates the Y terminal and also provides a cooling call to the heat pump or chiller control through the tekmarNet® communication. When operating a fan coil that uses both hot and chilled water, then the Cool Terminal Type should be set to H1. The thermostat activates both the Y terminal and the heating terminal device (zone valve or zone pump), as well as provides a cooling call to the heat pump or chiller control through the tekmarNet® communication. - Hydronic System Supply Pump —————————————
When connected to a tekmarNet® system control, the thermostat’s Cool Pump setting affects how the primary pump or mix pump on the system control operates during cooling operation. When connected to the boiler bus, the boiler system or primary pump is operated. When connected to the mix bus, the mix system pump is operated.
If the thermostat operates a motorized or thermal motor zone valve, the Cool Supply Pump setting should be set to On.
If the thermostat operates a thermal motor (wax actuator) zone valve, set the Cool Supply Pump Delay setting to On. This provides a three minute delay to allow the zone valve to open before the primary or mix pump is turned on.
In special applications with multiple zoning manifolds, the Cool Supply Pump setting can be set to Off. This allows a Zone Group Pump located on the Zone Manager, or Wiring Center to operate the pump for the manifold.
Floor Cooling
The thermostat has the option to support radiant floor cooling when connected to a heat pump control using tekmarNet® communication. The heating terminal unit type must be set to be hydronic (HYD), the floor cooling setting must be set to On and the heating system must be in Warm Weather Shut Down (WWSD). When the heat pump system control operates in cooling mode, all thermostats set for floor cooling on the tekmarNet® bus all activate the first stage heating contact (H1) at the same time to allow chilled water into the system. The thermostat continues to operate the cooling until either the room temperature reaches the Set Heat temperature plus 3°F (Set Heat+1.5°C) or reaches a minimum temperature of 74°F. If only a floor sensor is installed, the floor cooling setpoint is 67°F (19.5°C).
Fan Operation
The thermostat normally operates the fan together with the heating and cooling systems. This is determined by the Fan Mode setting in the Adjust menu.
| Fan Mode | The fan operates with… |
| 0 | Not With Heating Nor Cooling (Only with fan button) |
| 1 | Cooling Only |
| 2 | Heating and Cooling |
| 3 | Heating Only |
The fan relay includes a post purge feature. After the heating is shut off, the fan continues to operate for 30 seconds. After the cooling is shut off, the fan continues to operate for 10 seconds.
The user can also select to operate the fan manually by pressing the Fan button.
This allows the user to choose between Auto and On. “Auto” allows the fan to operate together with heating or cooling but normally the fan is off. “On” forces the fan to operate continuously.
The fan button is inactive when the Fan Mode is 0 and Ventilation is set to Off.
Ventilation Fan
In order to provide ventilation to the building, the fan can also operate for additional time beyond what is required for the heating and cooling systems. Ventilation allows the user to select the fan to operate for a minimum percentage out of each hour. Options are 10 to 90%, in 10% (6 minutes per hour) increments, as well as Auto and On. This is available when the Ventilation setting in the Adjust menu is set to On. Once Ventilation is set to On, the Fan minimum run time percentage during the and events can be set so that the fan can operate on a schedule and/or together with scenes.
Schedules
Lowering the room temperature setting reduces the amount of fuel required to heat the building resulting in energy savings. Likewise, raising the cooling temperature results in energy savings.
This thermostat can follow a programmable schedule in order to automatically lower the room temperature setting. A schedule master such as a Timer 033 is required in order to gain programmable schedule functionality.
When operating on a programmable schedule, a 
symbol is shown, as well as a
or a 
. The or indicates the current operating temperature.
If a symbol does not appear, there is no schedule available.
| Display | Action |
|
Occupied temperature. No schedule. |
|
Unoccupied temperature. No schedule. |
|
Programmable schedule at occupied temperature. |
|
Programmable schedule at unoccupied temperature. |
When a programmable schedule is selected, there is a time delay for the temperature to change from the temperature to the temperature.
The thermostat uses Optimum Start to predict the heat up and cool off rate of the room. The optimum start feature allows the room to reach the set room temperature by the time set in the programmable schedule. This applies for both heating and cooling.
Scenes (System Override)
Scenes provide an easy way to save energy while away on vacation, or override a pre-set schedule when plans change. tekmarNet® devices such as a User Switch 479 provide scene adjustment.
This thermostat responds to the following scenes:
| Scene | Display | Room Temperature Setting |
| 1 | or or |
Follows a programmable schedule or operates at the occupied temperature. |
| 2 | Away | Away temperature. |
| 3 | |
Unoccupied temperature. |
