Mr Cool Heat Pump Thermostat Here are some thing you should keep in mind when you’re installing any programmable thermostat: do not install a thermostat on an exterior wall. if that wall is poorly insulated, your thermostat is going to think it’s either too hot or too cold. you’ll waste energy in summer and winter. which is bad. 8. for wiring, use only the cables specified. do not subject the terminal to external force. this could lead to the wire becoming damaged and result in fire. 9. refer to the wiring diagram included in this manual to connect the wired controller to the indoor unit. 10. the wired controller works in a low voltage loop circuit.
Mr Cool Heat Pump Thermostat Use wire cutters to cut off the wire end and then peel away about 1 in (25 mm) of the insulation layer. use a screwdriver to unscrew the terminal screw on the terminal board. use needle nose pliers to bend the solid wire into a ring that fits the terminal screw. form a proper ring and attach to the terminal board.
