A
Ambient Light stays On, Terminal "A" Has No Power
The ambient light comes on when terminal "A" is powered with 24 VAC. If there is also an induced
voltage on the wire to terminal "A" after the ambient light is turned on, and the light does not go off
when the 24 VAC is removed, it may be necessary to use a relay on this terminal to isolate the induced
voltage. Reports suggest that the mechanical cooling is locked off when terminal "A" loses the 24 VAC
power, it is just the ambient light itself that is latched on.
NOTE:
When finished ensure all pots and dipswitches are in the correct operating
positions. This is especially true for dipswitch 8.
