PROHIBITION

The product must not be applied for control of motors.

CLASSIFICATION

The product is a class II device (reinforced insulation) and the product must be connected to the following conductors:

Terminal 1 phase (F/Ll)

Terminal 2 neutral (N/L2)

INSTALLATION

Install the Product on to a wall or a terminal board with two screws in the “keyholes”, see figure 5.

THERMOSTAT POSITION WHEN APPLYING BUILT IN SENSOR

The thermostat is placed on the wall with free air circulation around it and should not be placed where it is influenced by other heat sources (e.g. the sun), draught from windows or doors, or by the outdoor temperature (outer wall).

THERMOSTAT INSTALLATION (Figures 1,2,3)

 1. Remove the thermostat knob (A)

 2. Loosen screw to remove cover.

 3. Connect cable from the rear as shown in diagram,

 4. The thermostat is placed in the wall socket -remount frame and cover. -reposition thermostat button.

APPLYING EXTERNAL SENSOR TO MTU WITH BUILT IN SENSOR

A floor sensor or remote room sensor can be applied instead of the built in sensor by removing the JUMPER J1, see fig. 2.

REMOTE SENSOR INSTALLATION

Remote sensor is placed in conduit which is embedded in concrete in the floor. The conduit end is sealed and placed as close to the surface as possible in the concrete layer, Sensor cable is extendable up to 50 m by separate power cable. Two conductors in one multiple cable, which e.g. are applied to supply the heating cable, must not be used. Voltage signals may occur which can interrupt thermostat operation. If a shielded cable is applied, then the shield must not be earthed but shall be connected to terminal 6. The optimum installation is achieved by a separate sensor cable which is installed in separate conduit.

MODES AND SETTINGS

TEMPERATURE SETTINGS

TSSHC-3IL has a scale range of +5/+40°C. Red LED indication when heating is on to assist adjustment of the thermostat. The thermostat is set at max temperature until the required room temperature has been obtained. Then turn back the thermostat until LED switches off. After one or two days fine adjustments may be necessary.

SETBACK TEMPERATURE

Setback temperature is energised by remote timer (see figure 3). Setback temperature is 5°C below the set temperature.

THERMOSTAT ADJUSTMENT

When the room temperature has been stablilised then the thermostat knob can be adjusted. Measure the room temperature with a thermometer remove the thermostat knob, and re position it so that it indicates the measured temperature The adjustments can be made in 3 C step,

ERROR CIRCUIT

TSSHC-3IL has a built in error circuit which deenergises the heating if the sensor is switched off or short circuited.
