REMOTE THERMOSTAT OPTION
All MAC models are capable of being factory equipped to operate with a remote located 24 volt thermostat. When
this option is used, the unit’s thermostat remains in the unit but no longer controls. Control is transferred to the re-
mote thermostat through the remote terminal block located behind the electrical access panel.
CAUTION:
Do not attach any power or “live” wiring to the terminal block. The unit’s internal 24 volt power sys-
tem will operate the remote thermostat.
EASY TO WIRE:
The 2 wires from the remote thermostat are routed through the cord storage box, through the neo-
prene bushing and attached to terminals 1 and 2 on the remote thermostat terminal block. Terminal 7 (blue) and ter-
minal 8 (white) complete the circuit for the remote thermostat. No additional wiring required.
CAUTION:
Do not remove or change the wires on terminals 3 (white) and 4 (blue). They must remain connected.
TO REVERT TO UNIT’S INTERNAL THERMOSTAT: When the remote
thermostat is no longer required it is easy to convert to internal thermostat con-
trol. Simply move the white wire from terminal 8 to terminal 6. Then move the
blue wire from terminal 7 to terminal 5. This completes the circuit for using the
unit’s thermostat.
