HVAC Selection
• Set the HVAC TYPE switch in the NORM position if you have
conventional natural gas, propane, oil, or electric heat. If you
have a HEAT PUMP system set the HVAC TYPE switch to HP.
• Set the HEAT SOURCE switch in the GAS position if you have normal gas or oil heat or if you have
a heat pump with gas or oil auxiliary heat. Put the HEAT SOURCE in the ELEC position if you have
normal electric heat or if you have a heat pump with electric auxiliary heat.
Install 3 AA Batteries
• Install 3 AA alkaline batteries [required] following
the marked polarity in the battery compartment.
Put the lower battery in negative end rst against
the spring, then push the positive end in. Then
insert the last 2 batteries as shown.
IMPORTANT: Press the RESET button (under
top cover) to implement the HVAC switch selections.
• With all the wires connected it is time to turn the AC power back on. Do this at the breaker you used
to switch it off. The 3M-30 will power-up in the control OFF mode. Your 3M-30 is not congured to
operate your HVAC system yet. You must now congure your thermostat for your HVAC system.
