Statement of use
This thermostat can be used with three AA batteries, 24 VAC (C wire), 24 VAC
adapter, heating and cooling systems, and millivolt heating. It cannot be used
with line voltage systems. This thermostat is digital and your desired heat or cool
temperatures can be set on the large touch screen with the +/- buttons. A
minimum 4-minute off time protects the compressor from damage.
This thermostat runs on three AA batteries. The thermostat can be externally
powered with a power source from 12 to 24 VAC or VDC, at 300 mA or greater. If
used, connect to the C and RH terminals (no polarity). The 24 VAC “C” wire is on
the other side of the 24 VAC heating transformer and can be found where the
other thermostat wires connect at the wall or at the furnace. Do not use the
common or ground side of the line voltage.
Wiring diagrams
Two-wire heat, gas millivolt or 24 VAC system (C, W, RH):
1. Connect the R (or RH) wire to the RH terminal. This connects the power.
2. Connect the W wire to the W terminal. This connects the heat.
3. Set the HVAC Type switch to NORM and the Heat Type switch to GAS.
Your HVAC system is now connected to the thermostat.
