Installing the COOL-1

1) The unit requires a 120 volt power supply. The device that will
be controlled must be 15-amps or less.

2) The COOL-1 is plugged directly into a wall outlet. The 6/32
screw provided with the unit can be used to secure the
COOL-1 to the wall outlet. (remove existing screw first)

3) Connect the device you are controlling into the receptacle on
the front face of the unit.

4) Turn the dial on the COOL-1 to the desired maximum
temperature setting. When the temperature rises to the setting,
what ever is connected to the COOL-1 receptacle will be
turned off until the temperature drops by 5’F. Once the
temperature drops to the lower level, the device connected is
re-activated.

Operating the COOL-1

Once the COOL-1 is plugged in and has power, the temperature

probe will read the air temperature. When the air temperature gets
above the setpoint, the device connected to the COOL-1 will be
DE-activated.
Since the COOL-1 has a 5 degree F deadband, when the
temperature goes 5 degrees below the setpoint, the COOL-1 will
turn ON the device connected to it.
The RED indicator light on the side of the unit turns ON when
the receptacle on the front of the unit is powered. When the light
is ON, the device connected to the COOL-1 will be operating.

Hi-temp shutdown

THIS COOL-1 is already configured to be a hi-temp
shutdown for HID lights.

It can also act as a heating thermostat. When the temperature in
the area rises, the device connected is turned OFF.
