Mechanical capillary thermostat
The MTIR electro-mechanical thermostats are constructed around a
fluid-filled capillary tube and sensor housing that transfers the chan-
ges in temperature to a change-over relay. In thermostats constructed
for wall mounting, the capillary tube is wound and mounted on top of
the housing. The relay is capable of breaking up to 15 A at 230 V AC.
It comes in a 1-step or 2-step model.
