Wanting some method of dehumidifying our GMC living area when it is cooler than what would require the aircon compressor to stay running I came up with this mod. The heat strip installed is not listed for our aircon but it can be made to fit. The plan was to use the original thermostat to control the heat element with an inverting relay. A side benefit would be the option to use it for dehumidifying by alternating the compressor and heat.
Operation is cool on heat off - just cools, heat on cool off -just heats, Cool and heat both on - compressor and heat alternate on the thermostat thus dehumidifying. We like it.
