position. |
2. Control Switch
The control switch has 3 positions, "ICE," "OFF," and "DRAIN." See Fig. 11.
a) ICE
When the control switch is in the "ICE" position, 24VAC is directed to control board K8 connector pin #1. 24VAC is present between control board K8 connector pins #1 (power) and
pin #2 (neutral).
b) OFF
When the control switch is in the "OFF" position, 24VAC is broken to control board K8 connector pin #1.

c) DRAIN
When the control switch is in the "DRAIN" position, 24VAC is directed to control board K8 connector pin #1. 24VAC is present between control board K8 connector pins #1 (power) and
pin #2 (neutral). Also, a 5VDC circuit is closed on control board K9 connector pins #1 and #2. This energizes an internal relay on the control board which allows 24VAC to the drain valve from control board connector K2 pin #10.
