meaning it can switch power between two different circuits

Unlike variable expansion valves

How do I confirm the 0

A technician should perform an amperage draw test or check for continuity across the leads to ensure the internal heating element has not reached an open-circuit state

Peco Controls TA155-017 Stat 320788-704 meaning it can switch powerThe Peco Controls TA155 017 is a heavy duty, vertical mount line voltage thermostat engineered to provide reliable on off control for valves, relays, and fan motors in demanding commercial environments. This analog fan coil thermostat is the direct performance replacement for the CTE 6111 10, streamlining retrofits in 2 pipe and 4 pipe HVAC systems without requiring complex rewiring.
