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

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
