These systems have no manual speed selection capability. The thermostat wires must be connected
directly to terminals C and T on the controller.
W35F and W50F
The thermostat wires must be connected with one wire to the “T” terminal on the Speed Board (or
Merlin II
if installed), and the other to the vacant terminal of the high temperature cut-out mounted on the
condensing coil. There is a factory installed white wire connecting the “C” terminal to the other
terminal on the high temperature cut-out.

10:6 Connections, Fan
The wires from the fan on air cooled condensing units will be factory installed on the terminals marked
“F” (Black or Blue), and “+” (Red). If the wires are reversed the fan will not run. The K50F and W50F
models have a small oil cooler fan installed. Full instructions are included with the W35F and W50F.
10:7 Connections, Pump
The W35F and W50F model use a 12v pump that must be connected through a relay (PN E251002)
that is activated from the fan terminals on the controller. This relay is supplied with W35F and W50F
compressors.
See separate instructions for wiring multiple W35 or W50 systems to one pump.
It is important to note that the output voltage at the fan terminals will be 12v even if the power supply
to the controller is 24v, so a relay with a 12v coil must always be used.
The W35F and W50F have temperature sensors on the water-cooled heat exchanger that is connected
in series with the thermostat and will stop the system if the cooling water flow is insufficient. Full
wiring instructions are included with the system.
