ReplyYou would use the accessory relay on the ABC control board within the Envision unit to control the bulb. There are dip switch settings to cycle the relay with the blower.

I have a WF Envision that use to have a UV bulb powered from the Intellizone panel. I unhooked it years ago when the bulb life was used up and I installed new Ecobee thermostats. I'd like to use it again but don't recall the proper connection on the Intellizone board to get power. I'd like the bulb to turn on when the fan runs. I do have a separate doorbell transformer I could power the UV light with but I'd like to try and have the bulb on when the fan runs and avoid the extra mess of wiring up a separate power source. Does anyone have experience with this board or similar setup.
Thanks.

I connected the leads of the UV bulb to the corresponding "R" and "C" pins via the accessory relay and it works like a charm, thank you for the suggestion.Originally Posted by sshaw

Good to hear it worked out for you.
This site is very active, but there's not much on here about GSHPs.
The forums on geoexchange.org seem are the best resource I could find for GSHP. There are some knowledgable folks on there.
