Thermostat Wiring

Thermostat Wiring

The HP-5 microprocessor control is designed to operate

with wall thermostats sold by Mammoth. It can be used

with other heat pump thermostats but some features

may not be available. Wiring from the thermostat is rout-

ed through an electrical knockout in the front of the unit.

See Figure 12 and Figure 13 on page 13. A remov-

able terminal block simplifies hookup. See Figure 20.

To remove it, gently pull it straight out from the control

board. Thermostat connections are made as described

in the following diagrams.
