Operating instructions
General introduction
Start up and automatic temperature regulation are imple-
mented by the ambient thermostat.
Locate the thermostat approximately 1.5 m. above floor level,
where no object prevents it from registering the true tempera-
ture of the room.
Do not place it on a wall where it will be exposed to direct
sunlight, or next to windows, air vents, etc. Before start up
connect the mains switch in order to eliminate the electrical
resistance of the compressor sump.
The compressor must not be started up until at least
eight hours have passed.
DSL ambient thermostat for 610 heat pump
This thermostat has been designed to proportion a precise
control of the ambient temperature and to give graphic
information of the mode in which the heat pump is opera-
ting.
It is a control with a Proportional-Differential-Integral re-
sponse which, in relation to the difference between the
programmed and the ambient temperatures, varies the on/off
cycles between 3 and 7.5 cycles per hour.
The liquid crytal display (LCD) normally indicates the ambient
temperature, mode of operation, and whether the heating or
cooling system is connected.
It allows for the selection of different set points for heating and
cooling, as well as the choice of °C or °F.
The operation of the fan can be set in continuous mode, or
automatic, switching off and operating in unison with the
compressor.
The controls are located underneath a cover which prevents
their manipulation by unauthorised personnel.
Operation and start up
Start up is implemented by the controls located on the
thermostat.
