Heating Differentials
Each heating stage has an adjustable differential and time delay setting to determine when the stage turns on. The heating stages Heat 4 to Heat 1 shut off are when they reach 1.5, 1.0, 0.5, and 0.0°F (0.75, 0.5, 0.25, and 0.0°C) of the Heat To setting respectively.

Radiant Floor Heating
Radiant floor heating is operated differently than other heating types due to the large time delays to heat and cool the slab. When Radiant Floor Heating is selected in the setup menu, the W1 relay oper-ates using Pulse Width Modulation. This improves comfort for radiant systems with high mass floors.

• 100% on time at Heat To setting -1.5°F
• 50% on time at Heat To setting
• 0% on time at Heat To setting + 1.5°F

Room Sensor and Averaging
The room temperature can be measured using a combination of the built-in and auxiliary sensors.

• Built-in room sensor only
• Built-in room sensor with auxiliary room sensor(s) (temperature is averaged)
• Auxiliary room sensor only

Floor Sensor for Radiant Floor Heating
If a floor sensor is connected, floor minimum and maximum settings are available. For a combination of air and floor temperature control, leave the internal air sensor on in the setup menu. A floor minimum can be used to prevent a fast drop in temperature caused by receding solar exposure. This operation is recommended for areas heated by afternoon sun through large windows. When the sun sets, it can take a long time for the floors to get warm again. This may cause the room to cool off too much in the early evening. A floor minimum setting can help with this condition by maintaining a floor minimum temperature. Keep in mind the floor minimum temperature will override the air temperature, and if set too high, may overheat the room. A floor maximum is recommended for rooms with hardwood floors. Setting floor minimum and maximum temperatures is a way of enhancing the comfort of the living space while protecting
floor coverings. If there are more than one floor temperature sensors, the temperature is averaged.

Cooling Differentials
The first and second stage cooling have adjustable differentials and time delay setting to determine when the stage turns on, and shut off when the room temperature reaches 0.5 and 0.0°F (0.25 and 0.0°C) above the Cool To setting respectively.

Heat Pump Balance Point
An air source heat pump’s Coefficient of Performance (COP) declines with falling outdoor air tempera-ture. The Balance Point is the outdoor temperature at which it is more economical to shut off the heat pump (relays Y1 and Y2) and operate the backup heating equipment (relays W1 and W2). This feature requires an Outdoor Sensor 070.

Dual Fuel
Dual fuel systems include a heat pump together with a backup heat source such as a furnace or a hydronic fan coil. When Dual Fuel is set to on, the heat pump (relays Y1 and Y2) is shut off whenever the backup heating equipment (relays W1 and W2) is operating.

Warm Weather Shut Down (WWSD)
The heating system can automatically shut off based upon the outdoor temperature and the WWSD setting. This provides a convenient way to shut off the heating system. The WWSD requires an Outdoor Sensor 070.

Cold Weather Shut Down (CWSD)
The cooling system can automatically shut off based upon the outdoor temperature and CWSD setting. This prevents unwanted cooling during the winter. The CWSD requires an Outdoor Sensor

Relative Humidity Operation

Relative Humidity Sensor
The thermostat includes an internal relative humidity (RH) sensor and has the option to connect to an external RH sensor. The installer has the option to disable the internal RH sensor when an external RH sensor is installed. When both the internal and external RH sensors are enabled, the RH reading is averaged.

Humidifier Operation
The thermostat controls the relative humidity (RH) by operating either the Accessory 1 or Accessory 2 relays. This is an installer configurable setting. When the RH is below the Humidify To setting by 3%, the Accessory 1 or 2 relay is closed to operate a humidifier. The humidifier is shut off when the RH reaches the Humidify To setting. The thermostat can operate 3 types of humidifiers:

The thermostat can operate 3 types of humidifiers:

• Stand Alone – The humidifier is not connected to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
• Steam – The steam humidifier is ducted to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
• Requires the system fan to turn on when operating. Evaporative – A drum style humidifier which requires the heating system to operate to evaporate the water.
• This system requires the system fan to operate.
• The thermostat Mode must be set to Heat or Auto.

Humidifier Window Protection
During cold weather, condensation will form on windows when the relative humidity (RH) is too high. The optional window protection feature automatically calculates the indoor dew point based upon the outdoor temperature and the quality of the windows installed. The humidifier is then operated to the highest possible RH that is below the Humidify To setting. This feature requires a wired outdoor sensor to be installed.

Dehumidifier Operation
The thermostat controls the relative humidity (RH) by operating either the Accessory 1 or Accessory 2 relay. This is an installer configurable setting. When the RH is above the Dehumidify To setting by 3%, the Accessory 1 or 2 relay is closed to operate the dehumidifier. The dehumidifier is shut off when the RH reaches the Dehumidify To setting.
The thermostat can operate 2 types of dehumidifiers:

• Stand Alone – The dehumidifier is not connected to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
• DX Coil – The HVAC cooling system is used for dehumidification.
• The Accessory 1 or Accessory 2 relay activates the DHUM operation on the air handling unit to operate the system fan at low speed.
• The cooling compressor Y1 and Y2 relays are operated. The chilled DX coil condenses moisture from the air.
• The cooling system can over cool the room temperature by 2°F (1°C) during the dehumidification

HRV / ERV Ventilator Operation
Ventilation with fresh outdoor air is important for maintaining indoor air quality. The thermostat can operate a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) on a timer by closing the Accessory 1 relay to operate the ventilator fan at low speed.

Heat Pump Loop Valve Operation
The thermostat supports water-to-air heat pump systems that absorb or reject heat to a hydronic building loop. Whenever the heat pump compressor Y1 or Y2 relay is turned on, the Accessory 1 relay closes to open a hydronic zone valve. This allows variable-speed pumps on the hydronic loop to operate at lower speeds when the heat pump is off, thereby saving electrical energy.

Limited Warranty and Product Return Procedure

Limited Warranty The liability of tekmar under this warranty is limited. The Purchaser, by taking receipt of any tekmar product (“Product”), acknowledges the terms of the Limited Warranty in effect at the time of such Product sale and acknowledges that it has read and understands same. The tekmar Limited Warranty to the Purchaser on the Products sold hereunder is a manufacturer’s pass-through warranty which the Purchaser is authorized to pass through to its customers. Under the Limited Warranty, each tekmar Product is warranted against defects in workmanship and materials if the Product is installed and used in compliance with tekmar’s instructions, ordinary wear and tear excepted. The pass-through warranty period is for a period of twenty-four (24) months from the production date if the Product is not installed during that period, or twelve (12) months from the documented date of installation if installed within twenty-four (24) months from the production date.

The liability of tekmar under the Limited Warranty shall be limited to, at tekmar’s sole discretion: the cost of parts and labor provided by tekmar to repair defects in materials and/or workmanship of the defective product; or to the exchange of the defective product for a warranty replacement product; or to the granting of credit limited to the original cost of the defective product, and such repair, exchange or credit shall be the sole remedy available from tekmar, and, without limiting the foregoing in any way, tekmar is not responsible, in contract, tort or strict product liability, for any other losses, costs, expenses, inconveniences, or damages, whether direct, indirect, special, secondary, incidental or consequential, arising from ownership or use of the product, or from defects in workmanship or materials, including any liability for fundamental breach of contract. The pass-through Limited Warranty applies only to those defective Products returned to tekmar during the warranty period. This Limited Warranty does not cover the cost of the parts or labor to remove or transport the defective Product, or to reinstall the repaired or replacement Product, all such costs and expenses being subject to Purchaser’s agreement and warranty with its customers. Any representations or warranties about the Products made by Purchaser to its customers which are different from or in excess of the tekmar Limited Warranty are the Purchaser’s sole responsibility and obligation. Purchaser shall indemnify and hold tekmar harmless from and against any and all claims, liabilities and damages of any kind or nature which arise out of or are related to any such representations or warranties by Purchaser to its customers.

The pass-through Limited Warranty does not apply if the returned Product has been damaged by negligence by persons other than tekmar, accident, fire, Act of God, abuse or misuse; or has been damaged by modifications, alterations or attachments made subsequent to purchase which have not been authorized by tekmar; or if the Product was not installed in compliance with tekmar’s instructions and/or the local codes and ordinances; or if due to defective installation of the Product; or if the Product was not used in compliance with tekmar’s instructions.

THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, WHICH THE GOVERNING LAW ALLOWS PARTIES TO CONTRACTUALLY EXCLUDE, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, DURABILITY OR DESCRIPTION OF THE PROD-UCT, ITS NON-INFRINGEMENT OF ANY RELEVANT PATENTS OR TRADEMARKS, AND ITS COMPLIANCE WITH OR NON-VIOLATION OF ANY APPLICABLE ENVIRONMENTAL, HEALTH OR SAFETY LEGISLATION; THE TERM OF ANY OTHER WARRANTY NOT HEREBY CONTRACTUALLY EXCLUDED IS LIMITED SUCH THAT IT SHALL NOT EXTEND BEYOND TWENTY-FOUR (24) MONTHS FROM THE PRODUCTION DATE, TO THE EXTENT THAT SUCH LIMITATION IS ALLOWED BY THE GOVERNING LAW.
Product Warranty Return Procedure All Products that are believed to have defects in workmanship or materials must be returned, together with a written description of the defect, to the tekmar Representative assigned to the territory in which such Product is located. If tekmar receives an inquiry from someone other than a tekmar Representative, including an inquiry from Purchaser (if not a tekmar Representative) or Purchaser’s customers, regarding a potential warranty claim, tekmar’s sole obligation shall be to provide the address and other contact information regarding the appropriate Representative.
