- This thermostat should be limited to a maximum of 1.5 amps; a higher current may cause damage to the thermostat.
On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below.
- Locate the thermostat on an inside wall, at about 5 ft. (1.5m) above the floor, and in a room that is used often.
- Do not install it where there are unusual heating conditions, such as direct sunlight, near a lamp, television, radiator, register, fireplace, on a wall opposite a stove, or that carries hot water pipes.
- Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room, or in a draft from a stairwell, door, or window.
- Do not locate where air circulation is poor, such as: in a corner or alcove, or behind an open door.
- Do not locate in a damp area. This can lead to corrosion that may shorten thermostat life.
- Do not install the unit until all construction work and painting has been completed.
REMOVING THE OLD THERMOSTAT:
- Switch OFF the electricity to both the furnace and air conditioner; then proceed with the following:
- Remove the cover from old thermostat. Most are snap-on types and simply pull off, some have screws on the sides, and these must be loosened first.
- Take note of the letters printed near the wire terminals. Attach labels (enclosed) to each wire for identification by terminal letter, not color.
- Make sure the wires do not fall back inside the wall. Remove and label one wire at a time, and do not allow the wires to touch each other or any parts of the thermostat.
- Loosen all screws on the old thermostat and/or base, and remove it from the wall.
Be careful not to drop the body or disturb any of the electronic parts.
MOUNTING THE NEW THERMOSTAT:
- Strip insulation leaving 3/8 in. (9.5mm) of bare wire on the ends and clean off any corrosion present.
- Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat while in use.
- Pull your new thermostat apart by applying pressure to the thumb tab on the bottom edge of the unit. While pressure is being applied to this release latch, pull the two halves of the thermostat apart near the bottom edge.
- Hold the base against the wall. Route the wires through the larger hole adjacent to the terminal block. Position the base for the best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.
NOTE: If you are mounting the base to a soft material like plasterboard, or if you are using the old mounting holes, the screws may not hold. Drill a 3/16-in (4.8mm) hole at each screw location, and insert the plastic anchors provided. Then mount the base as described below.
CONNECTING THE WIRES:
- Clean bare wire ends must be inserted between the black clamp plate and the brass terminal as shown here.
- Securely tighten all electrical terminal screws (even unused ones).
Complete heating or cooling system wiring can be found in the WIRE IDENTIFICATION AND WIRING SCHEMATICS section of this instruction sheet. The schematics show system components for brand new installations or for un-referenced wires.
- If batteries are presently installed, remove them from the thermostat before proceeding with changing any of the options listed below.
- A table similar to the one shown below is printed on the thermostat’s circuit board. There may be minor differences present in some of the wording of your specific model, but the function of each option will be the same.
There are four (4) headers (or jumpers) located inside the thermostat at the rear of the circuit board. These settings can be changed from their default values by removing the corresponding black jumper cap and reinstalling the cap so that it is positioned on the adjacent pair of metal pins. A change to ANY of the option jumper settings will not be recognized unless the thermostat has been without battery power for at least 2 minutes, and then power is restored again. Each of these jumpers changes a different setup option. The choices for these options are listed in a table printed on the circuit board and are also printed adjacent to each individual setting jumper.
JP1 – FURNACE / HEAT PUMP SYSTEM TYPE:
This setting tells the thermostat about the type of heating and cooling equipment that it is controlling so that the system is operated properly. There are two operating modes based on your system type, “Furnace (FURN)” or “Heat Pump (HP)”. If you have a Furnace, ensure this is set to “Fn”. If you have a Heat Pump, ensure this is set to “HP”.
JP2 – FAHRENHEIT OR CELSIUS DISPLAY FORMAT:
This setting controls whether the temperature is shown in degrees °F or °C on the LCD display screen.
JP3 – GAS / ELECTRIC FAN OPERATION:
This setting defines the fan operation while in Heat mode, and when the fan is in Auto.
- GAS: Use this setting if you have a Gas or Oil heating system. In the GAS setting, the heating system itself controls the operation of the blower fan (if equipped).
- ELECTRIC: Use this setting if you have a Heat Pump or Electric heating system. In the ELEC setting, the heating system requires the thermostat to control the operation of the blower fan.
If you have an Electric Heat system and the blower does not operate after installation, locate the “Gas/Electric” option jumper and ensure that it is in the “Electric” position.
JP4 – [B] OR [O] TERMINAL USAGE OPTION:
This setting determines how the thermostat will use the shared B/O terminal connection on the back plate. Choose the UP (B) position to have the B/O terminal powered while in heat mode, and un-powered while in cool and off modes. Choose the DOWN (O) position to have the B/O terminal powered while in cool mode, and un-powered while in heat and off modes.
COMPLETING THE INSTALLATION
Once all optional jumper settings have been performed as described in the previous section, please ensure that the thermostat has been without battery power for at least 2 minutes. Now install new batteries into the thermostat. When installing batteries, use two new Energizer® or DURACELL® “AA” size alkaline batteries only. Ensure that the batteries are installed in the proper direction as per the markings shown in the battery tray.
Install your new thermostat onto its base. To do this, start with the bottom tilted out towards you at first, and line up the two holes in the top of the thermostat with the two hooks on the top of the back plate. Slowly pivot the bottom of the thermostat towards the back plate and push firmly on the bottom half of the thermostat until it is securely latched to the back plate. If the two thermostat halves do not latch easily, remove and try again. Do not attempt to force them together.
Before use, remove the plastic film (if present) that is protecting the LCD display screen.
Turn the electrical power back ON to both your heating and/or air conditioning systems. Verify that both systems (and the blower fan if used) are operating properly. When set to a high temperature, the heating system should provide warm air after a short time in Heat Mode. Likewise, a cooling system should provide cool air after a short time when set to a low temperature in Cool Mode. Usually, sound from the furnace and/or air conditioning units can be heard while either is running. If your system uses a blower fan, the rush of moving air should be heard within a short time after either has been started. Your installation is now complete.

FRONT PANEL ITEMS
SYSTEM MODE SWITCH:
The MODE switch has three positions: HEAT, OFF, and COOL. In the winter, set the mode switch to HEAT to control your heating system; in the summer, set the switch to COOL to control your air conditioning. In the spring and fall, or when the windows are open, you can set the switch OFF.
When the system mode switch is in the OFF position, it is normal for the system’s blower fan (“G” terminal if used) to still become activated depending upon the position of the FAN mode switch (see below).
FAN MODE SWITCH:
The FAN switch has two positions: AUTO and ON.
- In the AUTO position, the operation of the blower fan is determined only by the on/off cycling of the heating and cooling systems.
- When the FAN switch is in the ON position, the system’s blower fan will be commanded ON, and remain ON while the FAN switch is in the ON position (this also includes when the System Mode Switch is in the OFF position).
The FAN switch only works if your system provides a wire for the thermostat’s “G” terminal.
There are two push buttons to the right of the unit’s display screen. These are used to adjust the set point temperature.
While in HEAT or COOL mode, a single press on either the UP or DOWN button causes the word “SET” to appear on the screen. Once “SET” is present, the set temperature value starts flashing and the set point temperature can be altered by pressing either the UP or DOWN button once per degree of change or by holding either button for at least two seconds to automatically increment the set point quickly in the associated direction.
Based upon the relationship of the set temperature to the displayed ambient room temperature, the thermostat will engage either the W1 terminal in heat mode or the Y1 terminal in cool mode, if a temperature demand is present.
(For the PSD022Ba model only):
If there is a large thermal demand present that is greater than the first stage of heating (W1) or cooling (Y1) can accommodate, then a second stage of heating (W2) or cooling (Y2) will be activated. When the second stage of either heating or cooling becomes active, the word “AUX” will be shown on the display screen. There is approximately a 4-minute delay that is enforced between the activation of the first stage and the second stage of heating or cooling.
Pressing either set temperature button will illuminate the display for easier viewing in dim light conditions. The light will remain on for approximately 12 seconds. While the light is illuminated, pressing any of the three push buttons will continue the lighting and remain on for approximately 12 more seconds.
MINIMUM RUN/OFF TIME:
This is determined by the thermostat and controls the minimum length of time that the thermostat must remain with Heat or Cool either On or Off, before it will automatically switch to the alternate On or Off state. This feature prevents rapid or short cycling and provides compressor protection for cooling equipment. The time amount for this delay is fixed at 5 minutes between on or off-load changes.
BATTERIES AND MAINTENANCE
The batteries in the thermostat should be replaced AT LEAST once per year, or sooner if the “LO BAT” battery symbol appears in the lower right portion of the display screen. To replace the batteries in the thermostat, remove the thermostat’s body from the wiring base plate attached to the wall by pressing the thumb latch at the bottom center of the unit and swinging the front body out towards you, up and away from the base. Remove the used batteries from the battery tray and discard them appropriately.
Install two new Energizer® or DURACELL®, “AA” size Alkaline batteries into the battery tray. Observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, hang the top of the unit by the tabs at the top corners of the base, and then snap the bottom of the unit into place. Do not use unnecessary force. If the body does not snap into place easily, remove the body, re-hang it from the tabs at the top, and try again.
