Read This Before Installing Thermostat IMPORTANT Read the entire installation section of this Owner’s Manual thoroughly before you begin to install or operate your Hunter Thermostat. 2 SYSTEM COMPATIBILITY Your Thermostat is designed to operate with most gas, oil, electric, or 2-wire hot water heating and air conditioning systems. It will also operate single-stage heat pumps that do not have auxiliary or emergency heat.
TEMPERATURE RANGE Your thermostat can be programmed between 45°F and 95°F (7°C and 35°C). However, it will display room temperatures from 15°F to 99°F (-9°C and 37°C). “HI” will be displayed if the temperature is higher than 99°F (37°C), and “LO” will be displayed if the temperature is lower than 15°F (-9°C). 6 AUTO RECOVERY Your thermostat is set from the factory to gradually recover the room temperature from an energy saving program to your comfort program.
REMOTE SENSORS (does not apply to thermostat model 44660) Your thermostat can support 3 remote sensors that will measure the temperature from three different locations - two indoor and one outdoor. To configure your thermostat to work with the remote sensors, follow the instructions for Sensor Channel selection on page 14 of this manual. To configure the remote sensors, consult the Remote Sensor Instruction Manual.
Installation What You Need This thermostat includes two #8 slotted screws and two wall anchors for mounting. To install your thermostat, you should have the following tools and materials.
