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.
KTO 011: Thermostat (normally closed); contact breaker for regulating heaters. The contact opens when tempe
rature
is rising.
KTS 011: Thermostat (normally open); contact maker for regulating of filter fans and heat exchangers or for swit
ching
signal devises when temperature limit has been exceeded. The contact closes when temperature is rising.
> Large setting range
