Installation Instructions/User guide

Type 3IL with air sensor or floor sensor

TSSHC-3IL is an electronic heating thermostat designed to be installed in a standard single gang electrical box and requires no maintenance. 

A LED illuminates to indicate call" for heating, this also aids in system testing. An ON/OFF selector switch on the front of the cover makes system operation extremely simple.

FLOOR SENSOR INSTALLATION (where applicable)

The sensor shall be mounted in a conduit which should be sealed and placed as high as possible in the concrete, etc. The sensor is UL and cUL approved regarding the isolation test. The sensor wiring may be extended up to 150' (50 m) using 18 gauge wire and the wiring resistance shall not exceed 20 ohms. Sensor wires must be kept in a separate conduit, away from all other wiring. The sensor and wires must be protected from damage during the installation. If shielded wire is used, it must not be grounded but connected to terminal 6 on the thermostat.

ERROR DETECTION (floor sensor model only) The 3IL has built-in error detection which will de-energize the heating circuit if the sensor is damaged or if it detects an open or shorted sensor circuit.

CAUTION!

Disconnect all electrical power prior to installing or servicing this unit.

THERMOSTAT INSTALLATION (fig. 1-3)

1 . Remove thermostat knob, noting the position (A).

2. Loosen screw to remove frame and cover (B).

3. Attach wiring from the rear of the thermostat according to the wiring diagram (fig. ???)

4. The thermostat is mounted in a single gang electrical box - re-install frame and cover - re-install the knob in the proper position

TEMPERATURE SETTING/ADJUSTMENT

Adjust the temperature knob to the desired room or floor temperature, if after a few days you find the temperature to be different from the setting, adjustment can be made as follows: Measure the room temperature with thermometer, remove the knob without rotating it, then reposition the knob according to the measured temperature on the scale and re-install it.

MAXIMUM/MINIMUM TEMPERATURE LIMITATIONS

Behind the knob there are red and blue locking rings held in position by a screw. To set the limitations, loosen the screw (C) and adjust the red limit ring to the desired maximum, set the blue ring to the desired minimum temperature, then retighten the screw. The knob must be reinstalled exactly as it was removed.
