Wiring up thermostat
Posted: Thu Feb 21, 2008 9:30 am
I have a question about instalation of a thermostat.
First off I have yet to find the exact model number on the furnance but is a 17Kw unit in the EB series I believe. This unit was taken out of a mobel home and is now being used to heat a office area. This is being used for heat only and not connecting in to any AC unit.
The wires were never marked on the thermostat when removed so not sure which control what. I have 4 Wires red, green, black, white that come out.
I purchased a Hunter 40020A manual thermostat for heating system only. This unit ony has place for 2 wire; a W and RH area. I currently have the White in the W and Red in the RH area with the green and black leading no where. Thermostat does activate. Blower turns on and then warm air moves out. I have about 95 degree air coming out right into the box at teh heating coils. Is this sound about right or is only one stage of heating unit working? I have let run for about 1 hour intervals and no build up of higher tempatures. Is there a way of testing which elements are on with a volt meter? Can this 2 wire system be used or do I need one for heat/cooling still? If can be used, which 2 wires need to be connected if not connected right?
any help with this would be great.
