Generally applicable rules
for correct utilization of this control system

The expression "
heating = active
" in the linking formulae relates only to the release
specified in the "
PUMP
" menu or heating pump blockade conditions, but not however
to a possible switching off or release of the heating pump via a minimum threshold
value.

If no room sensor is used, the room influence
RI
in the menu
MIXER
must be set to
Zero
and the sensor
S1
in the
SENSOR
menu set to
FIXED VALUE (e.g. 20°C)
.

For use with floor and wall heating systems a safety thermostat is mandatory as re-
quired for conventional heating control units. To avoid consequential damage this has
to switch off the heating circuit pump independently of controller output in the event of
excess temperature.

The speed control is only meaningful for certain conditions. One is use it to limit the re-
turn temperature of the heating circuit. In some cases it can even replace the mixer by
using the speed control to hold the room temperature constant at the temperature
specified in the time program.
In some cases it can even replace the mixer by using
the speed control to hold the room temperature constant at the desired temperature
(although without the time program)
