Heat Pump Programmable Thermostat Congratulations! Model 43168 Thank you for choosing a Climate Technology Corporation (CTC) programmable thermostat. Your new CTC thermostat will provide years of reliable service and year-round energy savings. Please read this manual before beginning installation and save this booklet for complete operation instructions. The CTC Technical Support Group is available from 8 am to 5 pm EST M-F. They may be reached toll-free at 1-800-676-7861. IMPORTANT INFORMATION ........
IMPORTANT INFORMATION 1.This thermostat is designed to work on the following systems: • Single-Stage Heat Pump • Mulit-stage Heat Pump (up to 2 heating and 2 cooling) 2.Temperature Range This thermostat can be set between 45°F and 95°F (7°C and 35°C).However, it will display room temperatures from 30°F to 99°F (0°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 30°F (0°C).
Wire Labeling • CAUTION! TURN OFF POWER TO THE HEAT PUMP SYSTEM BEFORE YOU ATTEMPT TO ACCESS THE THERMOSTAT’S WIRING. • IMPORTANT! BEFORE DISCONNECTING ANY WIRES FROM THE EXISTING THERMOSTAT, APPLY THE PROVIDED SELF-ADHESIVE LABELS TO THE WIRES. • Use the information in Table 1 below and the provided adhesive labels to label the wires. IGNORE THE COLOR OF THE WIRES since these do not always comply with the standard. If the terminal letter on the existing thermostat is. . .
Mount Wallplate • Remove the wallplate from the thermostat by pressing the release tab on the bottom of the thermostat. See Figure 2. Figure 2 • Position wallplate on wall and pull existing wires through the large opening, then level for appearance. If the existing mounting holes from the old wallplate line up with the slots in the new wallplate, then use the exisitng holes.
Connect Wires and Mount Thermostat to Wallplate • Match and connect the labeled wires to the appropriate coded terminal screws on the wallplate. See Figure 4. Ignore any wires which may be present, but which were not connected to the old thermostat. • On the back of the thermostat are the System Set-Up Switches. See Figure 5. (NOTE: For clarity, the illustration of the thermostat circuit board omits most of the circuit board components to clearly show the System Set-Up Switches.
• Insert the tabs on top of the thermostat body into the slots at the top of the wallplate. Press the bottom of the thermostat body into the snap on the bottom of the wallplate. (NOTE: Do not force the thermostat onto the wallplate, as the terminal pins may be damaged. If it does not snap properly, the thermostat may not work.) • Turn on power to the heat pump system.
