How to connect new thermostat to ducted heating and swamp cooler
I have a swamp (evaporative) cooler and ducted heater which have both been connected to the same thermostat remote control, a Bonaire Comfort Control remote.
The remote control has now broken, and I would like to connect both units to a new thermostat.
The wires available to connect to a new thermostat are brown, red, orange and yellow.
I was interested in purchasing a basic Honeywell system, however the wiring diagrams make no allowance for a brown wire (see picture). The retailer does not believe joint wiring on the Honeywell is a possibility.
In fact, I havent found any thermostats that make allowances for brown wires, other than the original Comfort Control remote, which is no longer produced.
I dont know what the brown wire is for specifically.
Has anyone had this same issue before? How to resolve it?
