9. Alarm Relay – The Alarm relay (ALM) is factory
connected to 24 VAC via jumper JW2. By cutting JW2,
ABC ALM becomes a dry contact connected to ABC
ALG. The Relay is field switchable between Factory
setting as an Alarm output or available for other uses.
10. Accessory Relay1 – A configurable, accessory relay
on the ABC is provided that can be cycled with the
compressor, blower, or the Dehumidifier (DH) input.
A third (factory) setting cycles the relay with the
compressor but delays the compressor and blower
output for 90 sec. Source pump or slow opening
solenoid valves in well systems or variable speed
primary pumping systems would be a prime use of
this feature.
