The temperature sensing element selection allows the user to tailor unit operation to specific application requirements. The easy-to-install HE-67xx comes factory calibrated; it can recover quickly from saturation or loss of power. These features reduce both of the amount of time needed to install and commission the unit and of the maintenance cost. Each unit contains a 1000 ohm nickel or platinum temperature sensor. An optional warmer/cooler or graduated scale temperature setpoint adjusts up to heat or down to cool.
A manual override PB allows the occupant to control local temperature. By activating this feature, the end user can signal the controller that the space is occupied after hours or on weekends.
Another new feature is the Dual Inline Package (DIP) switch, which programs the HE-67xx to either:
Disable the PB and LED indicator
Enable PB with LED indicator
Enable PB without LED indicator
The HE-67xx features a quick-mount design that saves time and simplifies installation. A mounting base and screws come with the unit so it can be mounted directly to drywall (spring clips provided) or a U.S. wallbox. All wiring connects to terminal blocks.
