requirements.
 If field supply is 208V the tap on the transformer primary winding must be switched from orange
tor red. See the wiring diagram.
The field power supply connection is at the compressor contactor, at the end of the line voltage control box.
Disconnect –
field provided external safety disconnect is required, see nameplate max amps.
Loop pumps –
control box, upper right, is the pump relay board with field terminal block connection for the
source loop pump station and where applicable the 2
nd
loop pump (load pump output applies only to water to
water series). These outputs are controlled by GEO Logic, but protected with 10-amp fusing.
Grounding
