This controller varies the proportion (length) of time the heater is in the "on" or "off" heating mode.  the heating application will deteremine the actual percentage setpoint required.  The controller does not use a temperature sensor and therefore satisfactory operation requires occasional supervision under changing load conditions.

•  Plug-in operation

•  Type K thermoucouple

•  Proportional controlling

•  8' power cord 2 and 4-pin plug assembly

  

Specifications:

•  Rated 22 Amps up to 277 VAC

•  Differential 6° F

•  Enclosure rates NEMA 3R, for outdoor use

•  Tinned copper bulb and capillary, 10' long

•  Single Pole Double Throw contacts

•  Three different temperature ranges: 0-150°F,
