Page 6: Application
1 Introduction Application Panel-mounting thermostats in the KM series are suitable for monitoring heat generators, boilers, heat exchangers and pumps in HVAC engineering. Cutting through or kinking the capillary of the KM series panel-mounting ther- mostat will lead to permanent instrument failure! Marking Version to DIN 3440: STB = protection temperature limiter... -
