Switchover Temperature (SW OVER)

This switch is shipped from the factory with a square “GAS” label. This label should be removed ONLY if a

secondary furnace is present and active in the system. The installer should remove the label and adjust this

switch only after reading this manual and understanding the operation of the switch. Select the OT temperature

to interrupt the compressor and transfer to the sequence shown on applicable mode Figures 2, 3, 4. This only

applies when a gas furnace is connected. For all non-SB configurations must be set to 0 position (disable). From

the factory, this switch is set to 0 (Disable).

0 = Disable 4 = 5° F

1 = -15° F 5 = 10° F

2 = -10° F 6 = 20° F

3 = 0° F 7 = 30° F

Strip Heat Enable/ Disable(AUX EL)

When equipped with an auxiliary strip heater, the AUX EL dial allows the EZGEO control to be configured to

enable the strip heat based upon the outdoor temperature (OT). Setting the dial to 0 = Disable, the strip heat will

not turn on unless W2 is energized. When W2 is energized, all strip heat stages are activated. Setting the dial to

7 = Enable, will activate all stages of the strip heat at the beginning of a heat call. Please note, the Enable dial

setting is typically only used during initial startup inspection, troubleshooting, or in special cases when strip

heat is needed to operate all the time. If AUX EL dial is set to enable during a heat call, all strip heat stages will

remain active until the end of the heat call regardless of where AUX EL dial is set back to.

Warning: Leaving the AUX EL dial set to the Enable position will lead to reduced system efficiency and

higher operating costs.

0 = Disable 4 = 0˚ F (default)

1 = -30˚ F 5 = 5˚ F

2 = -20˚ F 6 = 10˚ F

3 = -10˚ F 7 = Enable

Stat Override Timer (SOT)

Again, see the appropriate mode Figures 1, 2, 3, 4 for the sequence action after the SOT timeout (end). The

intent of the SOT is to take care of very unusual heat/cool conditions or building matching situations, the

general sequence relating to OT temperature should take care of proper thermostat cycling without ever

reaching SOT timeout (end). Thus, it is recommended the SOT be a high number.

0 = 30 minutes 2 = 180 minutes

1 = 90 minutes (default) 3 = 270 minutes

Efficiency Setting (Front Panel)

This applies to AUX EL module or supplementary

heating only, mode B. By adjusting this dial switch the

homeowner can boost the ST target temp.

A = ST target temperature

B = +5° F

C = +10° F
