Frost Master

The Frost Master is a user-friendly defrost controller (timer) which operates various control valves and fan relays to quickly and efficiently remove frost and ice accumulation from evaporator surfaces.

There are four easy-to-set defrost steps:

  1. Pump Out Hot Gas
  2. Equalize
  3. Fan
  4. Delay

This controller uses reliable, solid-state electronics with a precision quartz time clock and time interval adjusting slide knobs to sequentially operate through the four steps for smooth defrosting.

Each step is clearly indicated by a bright LED during operation. Terminals for optional sensor defrost initiation and termination are provided. A 24-hour quartz time clock facilitates simple setting in 15-minute increments of defrost start times.
