in one direction. (optional cable lengths are available)
■ Solenoid Valve (optional) -
Connect coil wires between the
solenoid valve and the valve power output terminals on the
back of the control module as identied in Figure 2 above.
Note that there is no polarity required between connections.

General Information
■ Alarm System - TempControl High Temperature Audio
Visual Alarm System will monitor, alert and alarm when
water temperature exceeds preset limit. It best ts
applications where there is a critical need to accurately
monitor and control warm or hot water temperature.
■ Solenoid Valve (optional) - When alarmed, the valve is
de-energized and closes to provide complete shutdown of
the water ow.
■ Relay (customer supplied option) - Installed relay enables
remote monitoring of alarm control module.
■ Caution Set Point - is the lower of the two set point
temperatures that alerts when the output water is
approaching an undesirable temperature limit.
■ Alarm Set Point - Once the output temperature reaches the
alarm set point, the system goes into full alarm mode.
Installation
Important: All piping should be thoroughly
ushed prior to installation to prevent debris from
interfering with the solenoid operation. Do not run
solenoid power and temperature probe through
same conduit.
Piping
■ Tee Fitting - Required; appropriate size tting for
application purchased seperately (see options).
■ Temperature Probe - Locate probe as far downstream from
mixing valve as is reasonably possible.
a. Slide connector nut and ferrule piece over the probe.
b. Slide probe 1/2” to 2/3” into the tee tting.
c. Slide the ferrule and connector nut down the probe sha
and tighten in place.
■ Solenoid Valve (optional, 12 VDC, 10 Watts, normally
closed) - Install valve directly before the temperature probe in
any orientation. Make note of the correct direction of the water
ow as marked on the valve.
Electrical
■ Mount the 4" x 4" supplied mounting box in a dry location
within wiring reach of the temperature probe and solenoid
valve if used.
■ Mount supplied transformer.
