Viewing the temperature of the remote transmitter:The local and remote temperatures display alternates every 8 seconds on the thermostat LCD screen. To view the remote transmitter temperature, press AHEAD on the thermostat. The temperature will be shown on the bottom pane and the Remote Temperature Display symbol (antenna) will appear indicating the temperature displayed is from the remote transmitter. If the bottom pane is already showing remote temperature (the Remote Temperature Display symbol already on), pressing AHEAD key will show the local temperature of the thermostat.Controlling the thermostat based on the remote transmitter temperature (Heating or Cooling):The thermostat can heat or cool your home based on the temperature transmitted by the remote, instead of the thermostat's own temperature. To begin, place the remote sensor in the part of the house you wish to use for temperature control. Press the ON/OFF button on the remote transmitter until the Remote Temperature Control symbol displays. The thermostat will now control the heating and cooling based on the temperature as sensed by the remote transmitter. (Note: If the local temperature on the thermostat and remote vary by more than 4 degrees, or either remote transmitter or thermostat battery is low, the remote function will be cancelled.)Remote Override:raise or lower the set temperature by up to 3 °C or 6 ° . Press the UP or DOWN buttons on the remote override value displayed as a plus or minus value on the LCD screen of the remote.

Replace with fresh alkaline batteries. Note: We recommend replacing the batteries at least once a year even if the battery symbol is not flashing.1) Check and ensure that the thermostat is set to the HEAT or AUTO mode.2) Check and ensure that the set temperature is higher than the current (room) temperature.3) You may have to wait up to 5 minutes before the heat will turn on. The thermostat has a built-in time delay to prevent undesirable on/off sequences.4) After a 5-minute wait, the heat should now be on. Whenever the heating system is running, the symbol will be animated.41
PROBLEM SOLUTIONHeat will not come on but thesymbol is animated.Air conditioning will not come on.Air conditioning will not come on but the symbol is animated.The thermostat turns the heating or cooling systems on before my programmed set times.Heating system seems to cycle too often.1) Check if the furnace switch and/or pilot flame is turned on, as it may have been turned off.2) Allow several minutes for the heating system to heat up and the fan to activate. Most heaters will heat up the system for a short while before warm air can be ventilated by the fan. Also check that the HE/HG setting is set correctly. (see optional settings)3) If the heat still does not come on, check the wiring installation again. 1) Check and ensure that the thermostat is set to the COOL or AUTO mode.2) Check and ensure that the set temperature is lower than the current (room) temperature.3) You may have to wait up to 5 minutes before the air conditioning will turn on. The thermostat has a built-in time delay to protect the air conditioner compressor from undesirable on/off sequences.4) After a 5-minute wait, the air conditioning should now be on. Whenever the cooling system is running, the symbol will be animated.1) Check if the air conditioning system’s main switch is turned on, as it may have been turned off.2) Wait several minutes for the air conditioning system to activate. If the air conditioning still does not come on, check the wiring installation again. This is normal if the Pre-comfort Recovery system is enabled. The Pre-comfort Recovery will activate the heating/cooling in advance of the actual programmed set time so that the room will be at the desired temperature at the start of the program time. See the “optional settings” section. Check and ensure that you have selected a Cycle Rate that matches your particular heating system.If you find it still cycling too often, you may wish to try a slower cycle rate or disable the cycling. When disabled, the thermostat will operate at a fixed span of (plus or minus) ±0.5°C (±1.0°F). For example, if the programmed temperature is set at 20°C (68°F), the thermostat will turn the heat on if the current (room) temperature falls below 19.5°C (67°F) and turn the heat off when the current (room) temperature reaches 20.5°C (69°F). See the “optional settings” section. 42
PROBLEM SOLUTIONThermostat is set on AUTO mode, but the thermostat does not seem to automatically change-over from HEAT to COOL or vice-versa.While adjusting the program temperature or program timesin the HEAT mode, you notice the changes affect the settings in the COOL mode; and/or vice-versaCannot change the thermostat scale from °C to °F or vice-versa.The thermostat has a built-in safeguard time delay of 30 minutes to prevent undesirable change-over sequences from HEAT to COOL or COOL to HEAT. For example, if the thermostat was just running the cooling system, it will take at least 30 minutes before it changes to heating. You may override this manually by pressing MODE to change the operation to HEAT or COOL only.The heating and cooling program times are linked, so same program start times (chosen for either heating or cooling) will automatically be applied to the other. When you set the HEAT and COOL program temperatures fairly close to one another, the thermostat automatically restricts the two temperature settings from getting within 3°C (6°F) of one another. The COOL temperature setting will always be at least 3°C (6°F) higher than the HEAT temperature setting. For example, if the initial COOL program temperature was set at 24°C (75°F) and you decide to adjust the HEAT program temperature to 24°C (75°F), the thermostat will automatically push the COOL program temperature up to 27°C (81°F) to prevent overlapping.Selecting the temperature scales is a one-time start-up process. After the first battery installation, you must HARD reset the thermostat and choose the desired display in °C or °F. Otherwise, you CANNOT change the temperature scale (°C or °F) later on unless you perform another HARD reset which will clear all the programs and thermostat settings.To perform a HARD reset and select °C or °F, first press and hold the HOLD, while at the same time press and release the RESET button on the back of the thermostat. The LCD screen will blank out momentarily. To select °F, select see the “optional settings” section. 43The thermostat is not receiving asignal from the remote transmitter.Re-do the “Lean Procedure” to ensure an RF signal is being transmitted from the remote sensor to the thermostat. (See “Remote transmitter” section)The clock symbol is flashing This indicates that the 3V (CR2025) lithium battery is low. This will not affect the normal operation of the thermostat, but it should be replaced to ensure memory backup is maintained. Replace thelithium battery with a screwdriver.
