• Page 10: Heating operation allows setpoints from 40 to 95°F (4.5 to 35°C). The Heat On symbol indicates when the thermostat is heating. Heating for freeze protection activates below 40°F (4.5°C), regardless of the mode. Cooling setpoints can be set from 45 to 100°F (7.0 to 38.0°C). The Cool On symbol indicates when the thermostat is cooling. The thermostat supports two heating system types: conventional and heat pump. Conventional heating systems include furnaces, air conditioners, and hydronic heating systems. Heat pump systems may include additional heat sources as backup and support up to four heating stages. The thermostat supports up to two heating stages, two cooling stages, a fan, and two accessory relays for conventional systems. Accessory options include humidifiers, dehumidifiers, and HRV/ERV ventilators.
• Page 11: When radiant floor heating is installed, it is always the first stage of heating, followed by the heat pump, and lastly any backup heating. Emergency Heat mode shuts off the heat pump relays and operates the auxiliary heat, which is usually more expensive. The first stage heat turns on when the air temperature falls 1.5°F (1°C) below the Heat To setting and shuts off when the air temperature reaches the Heat To setting. The second, third, and fourth stage heat each have an adjustable differential and time delay setting. 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, the W1 relay operates using Pulse Width Modulation. The thermostat can measure room temperature between -46 to 212°F (-43 to 100°C). Room temperature can be measured using a combination of built-in and auxiliary sensors. The thermostat includes options for accessories such as humidifiers, dehumidifiers, and HRV/ERV ventilators. The reversing valve can be set to O or B for heating and cooling operations.
• Page 12: Floor sensor for radiant floor heating The thermostat can measure floor temperature between -46 to 212°F (-43 to 100°C). Floor heating setpoint is adjustable from 40 to 95°F (4.5 to 35°C). A floor minimum can prevent a fast drop in temperature caused by receding solar exposure. A floor maximum is recommended for rooms with hardwood floors. Setting floor minimum and maximum temperatures enhances comfort while protecting floor coverings. If there are multiple floor temperature sensors, the temperature is averaged. It’s possible to heat a radiant floor while the cooling system is operating. The first stage cooling turns on when the air temperature rises 1.5°F (1°C) above the Cool To setting. Dual fuel systems include a heat pump and a backup heat source.
• Page 13: HRV / ERV ventilator operation is crucial for maintaining indoor air quality. The thermostat can operate a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) on a timer. The Accessory 1 relay operates the ventilator fan at low speed. The thermostat supports water-to-air heat pump systems. Heat is absorbed or rejected to a hydronic building loop. When the heat pump compressor Y1 or Y2 relay is activated, the Accessory 1 relay closes. This action opens a hydronic zone valve. Variable speed pumps on the hydronic loop can operate at lower speeds when the heat pump is off. This operation helps save electrical energy.
