temperature by means of an NTC sensor. The heat output is
switched on and off with a differential of only 0.4˚C. Red
LED indicates when heating is on.
Temperature Setback
Type OTN with setback mode 5˚C which is activated with
a day/week timer, e.g. MM-7595. The timer is programmed
with the required comfort and setback periods.
Housing IP21
Type OTN-1991H11 can be mounted in bathrooms and
other humid rooms.
Adjustment of the Thermostat
Temperature range +5/+40˚C for easy setting of required
temperature. With the locking rings behind the thermostat
button the min./max. temperature setting can be selected
