Cync Thermostat Wiring Configuration And Installation Guide These control the power, heat and fan. standard thermostats use 4 or 5 wires: r, w, g, y, and sometimes c. these control the power, heat, fan, and cooling. more advanced thermostats use 6 8 wires. the extra wires control additional hvac system features and settings, signaling a two stage cooling or heat pump system. What uses 6 wire thermostat wiring? heat pump systems with a c wire and advanced heating and ac require 6 or more wires. for example, a two stage heat pump, one with aux heat and or one that has a reversing valve that needs power all require 6 wire thermostat wiring or more (7 and 8 wiring follow). how to wire a 6 wire thermostat: 1).
Thermostat Wiring Explained If your heat pump is a 2 stage model, meaning it has low and high heat and cool modes, then you’ll need a 2 stage thermostat. a 2 stage thermostat has both a y terminal (stage 1 cooling) and a y2 terminal (stage 2 cooling), and both terminals receive wires. while both wires are typically yellow, wiring colors may vary. *old thermostat. The installers put in a single stage thermostat, so as far as i could tell it was running as a single stage. i saw that the original wiring consisted of 4 wires, and wanting to make use of the 2 stages of heating, i ran a 5 wire cable, so i have 9 wires total. for the thermostat, i have an energate foundation. it supports up to 2 stage heating.

Unscrew the two wires from the terminals. remove the motherboard of the old 2 wire thermostat and put the new 2 wire thermostat in its place. reconnect the red and white wire, tighten down the set screw, and put the control panel back on. test the 2 wire thermostat wiring by turning the furnace on.
