Principle of operation
The quartz clock thermostats MTRU-T (day clock) and
MTRU-W (week clock) are used to control the tempera-
ture of rooms in buildings. They can be used in
connection with electrical heating systems. The
temperature control range lies between 5°C and 30°C.
You can contribute to energy efficiency by using
the night-time (temperature) reduction function, which
may be controlled automatically. The day/night-time
temperature drop (night-time reduction) can be set
within a range of approx. 3 (degree) K to approx.10 K
using a potentiometer. Switch-over times (from day-
time to night-time temperature and vice versa) can be
freely selected.
Operating modes: night-time temperature
day-time temperature
automatic night-time reduction
Usage in accordance with application purpose
The MTRU-T (day) and MTRU-W (week clock) quartz
clock thermostats may only be used indoors for
controlling electrical heating systems and in an am-
bient temperature between 5°C and 30°C.
