KTO 011 / KTS 011
Applies to: 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.
