Need help "breaking" thermostat!


Hello everyone! I'm new to this forum and hoping that someone here can help me with a problem.

For a whole bunch of reasons that I won't disclose because I don't want to bore you guys, I want to tweak the thermostat attached to my central AC/heat system so that the air conditioning will NOT come on. I don't want to do anything to the heat or to the fan.

In other words, I need to "break" the thermostat if you catch my drift.

I removed the cover and saw a bunch of different colored wires and a circuit board but I really know nothing about HVAC .

I can tell you that the thermostat is a White Rogers model # 1F78 Non-Prgm.

So if anyone can tell me in layman's terms how to "break" my thermostat so that the AC will no longer work, I will be very grateful.

Furnace or heat pump?

If it's a furnace you can simply turn the central AC off at the disconnect out side near the unit or turn off the circuit breaker for the condensor unit.

Disconnect:


If it's a heat pump you'll have to disconnect the wire that controls the AC, below are links for wiring the thermostat, with these you should be able to figure out which wire to disconnect.
