velleman K2649 Thermostat with LCD Display Instruction Manual
Mounting
This thermostat exactly fits into the box type B2649.
In case you use this box, you can fit the sensor onto the pcb in such a way that it passes through the opening in
the side of the bottom. In this way, the sensor reacts more quickly and accurately upon the room temperature,
and it doesn't get influenced by the heat-dissipation of the transformer and such-like.
In case of panel-mounting, you may use a some what longer flat cable, so you can simply mount the pcb's
with their solder sides towards each other, and the connections are easily accessible.
You also could use screw connectors for the sensor connection. Wherever and for whatever application the
thermostat may be used, always take into account that the mounting of the sensor determines the quality of
the regulation: the quicker it reacts upon the changing temperature, the better.
In case of liquids, this is not such a problem: you can attach the sensor on the outside of the metal pipe or
boiler (you could use a little bit of heat-conducting paste), or make the sensor waterproof and plunge it into the
liquid.
Air however is a much worse heat-conductor, so that the body of the sensor does not heat up/cool down that
quickly. This can be improved by circulating the air around the sensor.
Especially in large rooms, which are heated by means of hot air, it can be interesting to place the sensor in
the (cold) air circulation, for instance nearby the air inlet of the convector.
The intake air (which has the actual room temperature) then makes the sensor warm up quickly as the room
temperature increases.
