Alternate Part #'s _PF1103MT, INT-30-738, INTPF1103MT

Product Description

Single Circuit Freeze Protections Controls
These Freeze Protection Controls are designed to protect the pool and spa equipment and plumbing against freeze damage. They turn ON the pump and the heater when the outdoor temperature drops below the temperature set by the user adjustable thermostat. Models without timer connect to a timing or switching device and together, they control operation of the equipment as well as protect it against freeze damage. Models with timer provide both automation and protection for the equipment. Please note: For 240v, a neutral must be installed for the PF1103MT. If no neutral is available, you would need the PF1102MT.

** PLEASE NOTE: If ordered, this mechanism may come with a mechanical timer, not a digital timer as pictured above. Intermatic has changed back to mechanical timer for these freeze protect mechanisms. Inyo Pools does not guarantee which timer type will be shipped. **

Is this interchangeable with the older mechanism that has the red dial?

Will this replacement mechanism fit into a T104R Timer Box? I live in an area that has periodic freezes and my old freeze protection was a separate device, outside of the box.

Hello Richard - The PF1103MT will fit in the box for the T104R.
