CONTRACTOR TIP:
TESTING AUTOMATIC TEMPERATURE CONTROLS To verify a control is opening and closing properly, disconnect
all power before testing. Testing must be performed with the sensing element at a temperature within the setting range of the control. For
most hydronic controls with a range of 100 to 240°F, a pan of hot water is sufficient to reach the control range.
Attach an ohmmeter or continuity tester across the Open on Rise contacts. Lower the temperature setting dial to the lowest setting.
If the lowest setting is below the temperature of the sensing element minus the differential of the control, the contacts should be open.
Raise the temperature dial slowly. When the setting is raised above the temperature of the sensor, the contacts should close.
