Is field calibration required

utilizing this 985-7031-03 switch provides the exact response time required for industrial-grade protection without the risk of drift associated with universal alternatives

It monitors outdoor temperatures and closes or opens a circuit to initiate defrosting or auxiliary heat

providing critical protection for high-output commercial heating systems

Can I use this as a rollout switch
