Hevac Digital Series
Programmable Temperature Controllers (Electronic)
The HE-DIGITAL is a fully programmable microprocessor based temperature controller. This controller
is intended for use in air conditioning applications where the control of On/Off stages of heating and
cooling and/or sequencing of modulating actuators is required.
The controllers five relays can each be assigned individual functions and characteristics and the two
analog output signals can also be programmed individually for start and range.
The HE-DIGITAL-TC also incorporates a two channel 365 day time clock with optimiser function.

Surface Mount Enclosure
The HTC temperature controller is primarily designed for the control of Heat and Cool air conditioning
units. Stage switch on points are individually adjustable with their On/Off status displayed via LED
indicators. The HTC controller is ideally suited for DIN rail mounting in a switchboard, or directly inside
the air conditioning unit if required.
