KTO 011 / KTS 011
Small Thermostat
Thermostat (NC): Thermostat opens on temperature rise – for regulating heaters or for switching signal devices. Comes with red temperature dial.
Thermostat (NO): Thermostat closes on temperature rise – for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.
- Compact design
- Wide adjustment range
- Color coded temperature dials
- DIN rail mountable

Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance
may change. This can lead to a voltage drop and / or self-heating of the contacts.

ZR 011
Dual Thermostat
The ZR 011 houses two separate thermostats, allowing the independent control of heating and cooling or other equipment.
Thermostat NC (normally closed): Thermostat opens at temperature rise – for regulating heaters or for switching signal devices. Comes with red temperature dial.
Thermostat NO (normally open): Thermostat closes at temperature rise – for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.
- NC / NO or NO / NO in one unit
- Separate adjustable temperatures
- Color coded temperature dials
- DIN rail mountable
