To connect the controller, refer to the wiring diagram enclosed with this
user's manual.
Set the voltage switch to the appropri-
ate line voltage.
Route the cables through the electri-
cal knockouts provided at the bottom
of the enclosure. Do not make addi-
tional holes in the enclosure, particu-
larly on the side of the enclosure
when using a computer communica-
tion module.
It may be necessary to install a trans-
former on the heating stage in order to
supply the correct voltage to the
heater.
Mounting Instructions
Remove the four screws in the front cover and lift the cover. Remove the
black caps located on the three mounting holes. Mount the enclosure to the
wall using three screws. Be sure the electrical knockouts are at the bottom
of the enclosure in order to prevent water from entering the controller. Insert
the screws into the mounting holes and tighten. Fasten the black caps
onto the mounting holes.

TO ADJUST THE HEATER OFFSET
The heater offset can be adjusted to 1°F(0.6°C) or 2°F(1.1°C):
Set switch # 6 to ON to adjust the
heater offset to 1°F (0.6°C).
Set switch # 6 to OFF to adjust the
heater offset to 2°F (1.1°C).
Locking the parameters prevents accidental or unauthorized modification
of the parameter settings. When the parameters are locked, only the room
set point and the points of the temperature curve (if the temperature curve is
deactivated), as well as the stage 1 minimum speed (as long as the
minimum speed curve is deactivated) can be modified. All other settings
can not be modified.
TO LOCK OR UNLOCK THE PARAMETERS
Set switch # 1 to ON to lock the parameters.
Set switch # 1 to OFF to unlock the parameters.
FACTORY SETTING: When the controller is shipped from the factory,
switch # 1 is set to OFF (the parameters are unlocked).
