Installation of Venstar T1100REC Wireless Receiver and T1100RF Thermostat
I am trying to install the Venstar T1100REC receiver in conjunction with the T1100RF thermostat. My current thermostat is a Honeywell TH4110D. The gas furnace is a Trane XB with a White-Rodgers 50A55-486 controller board. The old thermostat is wired as follows:
White wire - W
Green wire - G
Red wire - R (there is a metal jumper from R to Rc but no wire connected to Rc)
I wired the T1100REC as follows:
White wire - W1,O,B
Green wire- G
Red wire - R
After configuring the house code and device code to match (just confirmed default settings were OK) and turning up the heat a few degrees I could see that the call for heat lights and fan light came on the T1100REC. However, I got no burner or fan response from the furnace. Any suggestions? I have seen other users with the same thermostat (but with 4 or 5-wire setups) having success connecting a common wire. I thought of trying that but wanted some expert advice before proceeding.

Page 16 refers to power "sharing" if common isn't used.
I would connect common.

I see that there are several unused wires and that the C is not connected on the furnace controller board. Can i just hijack one of the unused wires and connect it to C at both ends?

Yep, you can just hijack one of the unused wires and connect it to C at both ends.
(wouldn't let me just say yep)

Venstar T1100rec manual isunclear - not related to my 2 wire replacement
I have a 2 wire connection, red, white. The instructioin in the mamual are completely confusing. The diagram does not work-no power results. The furnace is gas and has the 24 volt wiring to the thermostat apready onboard.
Help please- specifics if they exist and no, its not a manual that i need, just some help because the manual is so unclear on 2 wire gas diagram.

Welcome to the forums!! How do you have the Venstar T1100rec wired? Are you saying you already have a wire going to the C terminal? If so, you should have 24V between the R and C terminals on the thermostat.
