Typical hookup of multistage heat pump with auxiliary/backup heat (H/ heat pump). Powering the Thermostat There are two different ways to power the thermostat: Batteries (three AAA alkaline). 4 Vac ommon wire. Wiring 4 Vac ommon Wire the common side of the transformer to the screw of the thermostat wallplate. When installing in a single transformer system, keep jumper wire between the and c screws. When installed in a two-transformer system, use the common from the cooling transformer to connect to screw and remove the jumper wire between the and c screws. Inserting Batteries (Optional) If not using a 4 Vac ommon to power the thermostat, install three AAA alkaline batteries (included) in the back of the thermostat. Make sure the positive and negative terminals are oriented correctly, as marked on the device. See Fig.7. BATTEIES () M998 Fig. 7. Installing batteries on thermostat back. Mounting the Thermostat. Align the terminal screw blocks with the pins on the back of the thermostat.. Push the thermostat straight onto the wallplate. See Fig

9 TH80U AND TH8U TOUH SEEN POGAMMABLE THEMOSTATS OPEATION System and Fan Settings The System default setting is Heat and the Fan default setting is Auto. SYSTEM SETTINGS Heat: Thermostat controls heating system. Off: Both heating and cooling are off. ool: Thermostat controls cooling system. Auto: Thermostat automatically changes between heating and cooling systems, depending on indoor temperature. (See Installer Setup section.) Em Heat: Emergency heat cycles to maintain temperature. ompressor is locked out. (Used only for heat pump systems with backup heat.) FAN SETTINGS The Fan setting can be programmed into the thermostat schedule for each period (Wake, Leave, eturn, Sleep). See the Owners Guide for additional information. LED Indication (equires 4 Vac ommon onnection) An LED indicator is located in the upper right corner of the thermostat. It is only visible when lighted: It indicates when the thermostat is in the Emergency Heat mode. When in Em. Ht. mode, the L terminal is continuously energized and the LED is on. When the L terminal is wired to an equipment monitor, the LED signals when a check or fail signal is sent to the thermostat from the system. See Fig.. (This can occur only when the thermostat is not in Em. Ht. mode.) INSTALLE SETUP This Universal Thermostat works with many different system types. To operate correctly, the thermostat must be set up to operate the installed heating and/or cooling system. Installer Setup Menus Main Menu: Offers the most commonly used options. It is necessary to enter this menu to set the thermostat to the type of system it is operating. Many applications use only the Main Menu. egional Menu: Offers choices often changed due to a particular area or region. For example, temperature display in Fahrenheit or elsius is offered in this menu. Advanced Settings Menu: Offers more settings to fully customize the thermostat. Many of these settings do not require changing from the factory settings. Entering Installer Setup. Thermostat must be powered either with Alkaline AAA batteries or with 4 Vac ommon wire.. From the home screen, press System key. (Press Done or ancel key to return to home screen.). Five blank touch keys show on the bottom of the screen between the Done and ancel keys.

OPEATION IN EMEGENY HEAT MODE The balance point (outside) temperature is not used in the Emergency heat mode. When the thermostat is moved to the Emergency Heat position, the compressor is locked out. The first stage of heat is whatever is connected to the E terminal. The second stage of heat is what is connected to the Aux. terminal. Often there is only one source of non-compressor heat and the E terminal is jumped to the Aux. terminal.

When the outdoor temperature is above the Auxiliary Lockout Temperature, only the ompressor operates. See Fig. 4.

Operation in the Emergency Heat Mode Once the thermostat is placed into the Emergency Heat mode, the compressor and auxiliary lockout features are turned off. In the Emergency heat mode, the compressor is locked out. The first stage of heat is whatever is connected to the E terminal. The second stage of heat is connected to the Aux. terminal. Usually the emergency and auxiliary heat sources are electric strip heat in these cases. Dehumidification Droop ontrol The dehumidification control attempts to control to the user's humidity setpoint by turning on the air conditioner. In extremely high humidity conditions, the thermostat keeps the air conditioner running for up to F below the temperature setpoint. It does this while trying to achieve the desired humidity setpoint and balancing that with the temperature setpoint
