Electronic Zone Thermostat (Honeywell
T7067)
Each unit ordered with constant volume controls (in the
model number) is shipped with a Honeywell T7067
electronic zone thermostat. A Honeywell switching
subbase (Q667) is also included. The switching
subbase allows the operator to select the “System
Mode” of operation, i.e., Cool, Heat, Auto, or Off and
the “Fan Mode” of operation, i.e., On or Auto.
NNoottee:: As long as the status of the system is in an
occupied mode, the supply fan will operate
continuously. The fan will only cycle in the
“Auto” mode during unoccupied periods.
The zone thermostat should be located in an area with
good air circulation to enhance zone temperature
averaging. Position the thermostat about 54" above the
floor in a frequently occupied area.
Do not mount the thermostat where its sensing
element may be affected by:
• Drafts or “dead” spots behind doors or in corners;
