The Zone Control 367 is a microprocessor-based energy management control that uses PID
logic to control the temperature in up to 6 heating zones. Multiple zone controls can be daisy
chained together for up to 36 zones of heating. The 367 allows a variety of zoning options
including: single stage zones, two stage zones and modulating zones. The 367 is designed
to stagger zone operating times in order to minimize boiler short cycling and allow boiler
purging between cycles. The 367 has a built in night setback timer and a separate Optimum
Start / Stop feature for each zone. When the 367 is used with a tekmar reset control, the 367
provides indoor temperature feedback that adjusts the supply water temperature in order to
satisfy the zone with the highest heat load. Central ventilation, mechanical cooling and free
cooling systems can also be directly controlled through the 367.
