The setpoint is adjusted mechanically via a dial or screw on the thermostat body. Check the actual setpoint calibration on your unit — mechanical thermostats may drift slightly over decades of use and can be recalibrated.\u003c\/p\u003e\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:17px; line-height:26px; margin:24px 0 8px 0;\"\u003e\"Does this thermostat need external power to operate?\"\u003c\/h3\u003e\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003eThe sensing mechanism is entirely mechanical — the capillary bulb and diaphragm actuate the switch without any external power. However, the switched circuit itself carries whatever voltage and current your application requires.
