Installation Procedure

Figure #2
Shutter Bushing
Control Center
Freeze Control Display
The following example illustrates how the display will
look when the freeze protection feature is activated. In
this example, the freeze sensor was connected, enabling
the freeze protection feature. Circuits #1 & #3 were
programmed to come on during a
freeze
condition.
Aux #1 & #3
will blink indicating the control has activated
these two circuits due to a freeze condition. To override
the circuits during a freeze condition, simply press and
release each of the corresponding ON/OFF keys. This
will override the freeze control and turn the devices OFF.
The override will only last for one hour, so if the freeze
condition still exists after one hour, circuits #1 & #3 will
come back on.
The freeze protection stays enabled until the outside air
temperature exceeds the pre-set temperature set point
for more than one minute.
IMPORTANT NOTE
The freeze protection feature will not work unless you
have installed the freeze sensor probe. Refer to page 7
of this manual for ordering and installation instructions,
and step #10 for freeze programming instructions.
