Using The Thermostat - S&P EMIDUAL Installation Manual

The indicator led (D) gives different information by changing the way it lights on
and exactly:
- The light is on and red when the product is heating to reach desired temperature;
- The light is on and yellow if the desired temperature has been reached and the
product is ready to operate to comfortably maintain it to the desired value;
- The light continuously flashes in red colour if temperature electronic sensor is
broken. The product must be repaired by an authorised service only;

Using the thermostat

In a room with a temperature in excess of 30°C, the thermostat does not turn on
the appliance even if it is at maximum.
Vice-versa, in a room with a very low temperature (below 10°C), the thermostat
keeps the heater constantly on, even if it is at minimum.
To optimise use of the thermostat, proceed as follows:
- set the thermostat (C) to maximum and wait until a comfortable temperature is
reached;
- move the thermostat (C) to the left until functioning led (D) turns yellow;
- move the thermostat (C) to the right for a couple of millimetres;
- in this position, the thermostat will maintain the selected ambient temperature.
Using the pilot wire
If the product is fitted with a power cable without plug, it can also be controlled
with specific programmers. The behaviour of the product depends on the volta-
ge applied between the pilot wire and the neutral wire, as shown in the following
table:

Note: the STOP input signal on the pilot wire will switch off the product even
if the mode selector is NOT in the "PROG" mode.
