This device incorporates a digital temperature controller and a 24 hour timer. These functions operate independently and control separate relays. The settings may be locked and code protected to avoid changes from being made by unauthorized personnel.

Timer Relay:
Whenever the current time (time of day) falls between the “ON” and “OFF” times, the timer relay is energized.
Note that there are 2 “ON” and “OFF” times.
A manual override function is included to force the timer relay to remain energized for up to 24 hours.

  • device operates as 2 separate controllers in one.
  • single set point temperature controller (relay 1)
  • 24 hour timer with 2 sets of “on” and “off” times. (relay 2)
  • 5 year battery backup keeps clock running during power failures
  • ideal for spa bath applications
