Applicable to:
The mechanical thermostats KTO 111 and KTS 111 are two state regulators for use up to 5,000 meters in altitude, thanks to optimised air gap and increased creepage distance. By use of Push-In terminals the thermostat is wired tool-free. The Push-In terminals provide constant pressure on the wires to prevent them from coming loose (e.g. during transport).
KTO 111: Thermostat (NC); contact breaker for regulating heaters. The contact opens when temperature is rising.
KTS 111: Thermostat (NO); contact maker for regulating of filter fans and heat

The mechanical thermostats KTO 011 and KTS 011 are two state regulators used to control heaters, coolers, filter fans or signal devices.
KTO 011: Thermostat (normally closed); contact breaker for regulating heaters. The contact opens when temperature is rising.
KTS 011: Thermostat (normally open); contact maker for regulating of filter fans and heat exchangers or for switching signal devises when temperature limit has been exceeded. The contact closes when temperature is rising.

Applicable to:
The mechanical thermostat is a two state regulator with small hysteresis. The setting wheel has an anti frost assurance. The housing ensures an optimized air circulation around the bimetal.
STO 011: Thermostat (NC); contact breaker for regulating heaters. The contact opens when temperature is rising.
STS 011: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for switching signal devices when temperature limit has been exceeded. The contact closes when temperature is rising.

Tamper-proof (Pre-set) Thermostat FTO 011: Contact breaker/NC (red casing) for regulating heaters or for switching signal devices when temperature has fallen below the minimum value. The contact opens when temperature is rising.
Tamper-proof (Pre-set) Thermostat FTS 011: Contact maker/NO (blue casing) for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded. The contact closes when temperaure is rising.

Two thermostats in one casing:
Thermostat (contact breaker, normally closed) for regulating heaters. The contact opens when temperature is rising.
Thermostat (contact maker, normally open) for regulating filter fans and heat exchangers or switching signal devices when temperature limit has been exceeded. The contact closes when temperature is rising.
Heaters and cooling equipment can be switched independently from each other with a temperature offset as opposed to the usual change-over contacts.
