Prerequisite for a clean operation of your components is the right climate in your enclosure. The right climate can be attained by a temperature and moisture control system which is put in place. Thermostats KT 011, FTO 011/FTS 011, ZR 011, FZK 011, ET 011…
Thermostat “NC” (normally closed): Thermostat opens at temperature rise. Comes with a Red temperature dial.
Thermostat “NO” (normally open): Thermostat closes at temperature rise. Comes with a Blue temperature dial.
FTO 011/FTS 011
Tamperproof (Pre-set) Thermostat NC (normally closed): Thermostat opens on temperature rise (red module housing) – for regulating heaters or for switching signal devices when temperature has fallen below the minimum value.
Tamperproof (Pre-set) Thermostat NO (normally open): Thermostat closes on temperature rise (blue module housing) – for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded.
The FZK 011 mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices where a higher degree of sensing accuracy is required. An integrated resistor (RF) can be connected to improve the switch temperature difference (see Option note). The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.
ET 011 24VDC
The ET 011 is an electronic thermostat for regulating high performance DC 24 V equipment. Heating or cooling equipment, as well as signal devices, can be switched via the SPDT (change-over) contact. A relatively small hysteresis sets the ET 011 Thermostat apart from less accurate mechanical thermostats.
