Thermostat operating range limiting system - uses pair of stops to limit movement of thermostat setting control

摘要

The thermostat operating range limiting system is applicable to thermostats having a fixed operating range element (8) and movable setting element (1). The limit system uses a pair of stops (5) which can be inserted in various positions in the fixed operating range part of the thermostat. The movable element which carries an indicator (2) comes into contact with the stops which limit the regulating range of the thermostat. In an alternative form the fixed part (8) has an indicator (9). The moving part (10) is connected to the thermostat setting element which has holes (11) in it. Into these holes are placed the stops (12).
