Sequence of Operation

Heating and Cooling Operation

• The heating setpoint can be set from 40 to 95°F (4.5 to 35°C).

• The Heat On symbol is shown on the display when the thermostat is heating.

• The cooling setpoint can be set from 45 to 100°F (7.0 to 38.0°C).

• Heating for freeze protection is provided whenever the air or floor temperature falls below 40 regardless of operating mode.

•

The Cool On symbol is shown on the display when the thermostat is cooling.

The thermostat supports two heating system types: 1) conventional, or 2) heat pump.

Conventional Systems

A conventional heating system includes: furnaces, air conditioners, hydronic heating systems with baseboards, radiant floors, or fan coils and electric heating.

The thermostat supports up to two heating stages, two cooling stages, a fan and two accessory relays.

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 operates using Pulse Width Modulation. This improves comfort for radiant systems with high mass floors.

Room Sensor and Averaging

The thermostat can measure room temperature between -46 to 212°F (-43 to 100°C). 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

The thermostat can measure floor temperature between -46 to 212°F (-43 to 100°C). If a floor sensor is connected, floor minimum and maximum settings are available. The floor heating setpoint is adjustable from 40 to 95°F (4.5 to 35°C).

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.

It’s possible to heat a radiant floor while the cooling system is operating. This is desirable in locations such as kitchens and bathrooms. To use this feature, set the Warm Floor During Cooling on.

28

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 temperature. 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).

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.

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.

29

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:

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

- 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 connection to an Outdoor Sensor 070.

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

- The cooling compressor Y1 and Y2 relays are operated. The chilled DX coil

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.
