INTRODUCTION The Smart Temp 44-800 “Apollo” is a feature-rich touchscreen thermostat that can be battery powered or hardwired to the HVAC equipment. Using a common sense approach to the installation will ensure this product is installed properly and to the customer’s satisfaction.
GETTING STARTED As with any HVAC project, careful installation is the key to a successful outcome. Time taken during the installation process will be rewarded with fewer call-backs. The steps required to install the 44-800 thermostat are as follows: 1. Read and understand this Installation Manual and Thermostat User Manual. 2.
INSTALLING THE THERMOSTAT DISASSEMBLY There are two release slots located on the bottom of the thermostat. Gently push the flat blade of a small screwdriver into one slot at a time and pry upward until the catch disengages. Carefully swing the thermostat upward and away from the subbase. (Figure 1) THERMOSTAT LOCATION The 44-800 should be installed in a location that represents the ambient space temperature.

(Figure 2) Do not over tighten the mounting screws as the subbase may warp causing the improper seating of the thermostat connecting pins to the terminal blocks. Smart Temp Aust P/L Use a properly sized screwdriver and BATTERY COMPARTMENT back each screw terminal out (counter www.thermostat.com.au...
INSTALLING THE THERMOSTAT TERMINAL DESIGNATIONS Based on the 44-800 slide switch and installer option configurations, some terminals have multiple output functions. TERMINAL DESIGNATION Outside Outdoor Sensor Sensor Common Sensor Common Inside Indoor Sensor W2, Y2, Compressor 2, Aux, EH W1, Y3, Reversing Valve Y1, Compressor 1 24 Volt (Hot) 24 Volt (Common)
Even if the thermostat is hardwired, battery backup is essential to maintain the real-time clock in the event of a power failure. All other memory is non-volatile in the event of battery or primary power loss. (Figure 3) Smart Temp Australia P/L www.thermostat.com.au Y G Com R C...
SETTING THE SYSTEM SWITCHES The 44-800 contains a set of four system switches located on the thermostat printed circuit board. (Figure 4) The switches are used to match the thermostat with the HVAC system requirements. Refer to the system switch functions on the next page to properly configure the thermostat.
SYSTEM SWITCH FUNCTIONS SW 1 - Equipment Type Switch 1 sets the equipment type. For heat / cool equipment, set the switch to the OFF position (factory default). For heat pump equipment, set switch 1 to the ON position. SW 2 - Fan or Reversing Valve Heat Cool Logic (SW 1OFF).

Touch the UP and DOWN arrows to change the ‘A’ relay assignment. Note that selections change based on Heat / Cool or Heat Pump (Sw1) configuration.
INSTALLER SETUP MENU LOW BALANCE POINT SELECTION USING OUTDOOR SENSOR Menu 18:LB allows you to select a low balance point setting when the thermostat is configured for Fossil Fuel. When the outdoor temperature falls below the balance point setting, the compressor is locked out and only the fossil fuel furnace is used for heating.
INSTALLER SETUP MENU HIGH BALANCE POINT SELECTION USING OUTDOOR SENSOR Menu 19:HB allows you to select a high balance point setting when the thermostat is configured for Fossil Fuel. When the outdoor temperature rises above the balance point setting, the furnace is locked out and only the compressor is used for heating.

INSTALLER SETUP MENU FACTORY RESET Menu 21:RS allows you to reset the thermostat to the original factory defaults. To reset the thermostat, touch the UP and DOWN arrows and set to ON.
REMOTE SENSOR INSTALLATION REMOTE SENSORS There are two type of remote sensors. The RS-1 is a single sensor that can be used indoors or outdoors. The RS-2 contains two sensors. A combination of both sensors can be used for indoor temperature averaging with or without the onboard sensor. Use separate 18-2 shielded cable when wiring sensors.
REMOTE SENSOR INSTALLATION Locate the sensor in the same manner as the thermostat. Mount the sensor 300mm away from any outside wall. Do not install the sensor behind doors, in corners or other dead air spaces. Keep the sensor away from direct air flow, supply registers or near sources of heat such as lamps and appliances.
REMOTE SENSOR INSTALLATION USING MULTIPLE SENSORS FOR TEMPERATURE AVERAGING Multiple indoor remote sensors can be wired in series/parallel for temperature averaging. The total value of the sensors must equal 10kÙ @ 25° C. The onboard sensor is not part of the equation even if it is configured as part of the averaging circuit.
REMOTE SENSOR INSTALLATION OUTDOOR SENSOR WIRING When the RS-1 is used as an outdoor sensor, the 44-800 will display the outside air temperature as well as control high and low balance points for fossil fuel systems. Refer to 16:TT in the installer setup menu to select the proper sensor option. The outdoor sensor wires to the Sensor Common and Outside air terminals.
REMOTE OUTDOOR SENSOR INSTALLATION Mount the sensor on a vertical exterior surface below an overhang. Choose a location protected from direct sunlight and exposure to excessive moisture. Follow the same wiring procedures as installing an indoor sensor. TEMPERATURE SENSOR CALIBRATION CHART Temperature Resistance Temperature...
TESTING The 44-800 incorporates a short-cycle timer which can be disabled during testing by setting slide switch 3 to the ON position. Once testing is completed, the timer needs to be re- initiated by setting the switch to OFF. TESTING FAN OPERATION Touch MODE until the word OFF is displayed.
TESTING Touch MODE until Cool appears. Touch the DOWN arrow and lower the setpoint a few degrees below the space temperature. After a brief moment, the internal fan ‘G’ and cooling ‘Y’ relay will energize. The word Cool will flash. If the thermostat has been configured for two stage cooling, lower the set point a few degrees and the second stage cooling relay ‘A’...
TESTING conventional heat pump system with the exception that the heat pump is never allowed to run when the fossil fuel furnace is energized. Whenever the thermostat calls for second stage (auxiliary) heat, the compressor ‘Y’ relay is de-energized along with the fan ‘G’ relay and the ‘A’...
TESTING TESTING HIGH BALANCE POINT (Heat Pump or Fossil Fuel) High balance point is designed to prevent the auxiliary heat ‘A’ relay from energizing when the outdoor temperature is above the balance point setting. To test the high balance point setting, set 19:HB below the displayed outdoor temperature and force a call for second stage heating.
BASIC TROUBLESHOOTING SYMPTOM POSSIBLE FAULT AND REMEDY No LCD display If thermostat is battery powered only, remove battery compartment and check to see that the positive (+) and negative (-) ends of each battery are oriented properly. If thermostat is hardwired, remove the thermostat from the subbase and check for 24 Volts across terminals ‘C’...
