Need heat only; will this combo work? Have Goodman gas 2 stage Variable speed furnace model GMVC950704CXAB with CTK01 Thermostat without A/C compressor.
Will the Comfort Net 4 terminal connections R, C, and Data 1, 2 connected at thermostat and furnace run the heat without A/C unit connected? L
Low voltage cable shielded 4 wire with ground terminated with 4 position plug connectors both ends. Are any jumpers required and from ? to ? Cable ground wire connection to any teminals or just to furance frame/ thermostat box?
Yes, it will run it without an outdoor unit connected. Make sure your furnace is on a dedicated line voltage circuit and is properly grounded. It won't require shielded cable, a piece of 18/5 stat wire is fine. Hook up your four pin harness from the furnace to the thermostat. It's as simple to wire as any stat available. The ONLY thing you have to ground is the furnace to it's dedicated line voltage circuit, nothing on the 24V side.
