Features overview

7 day schedule models, 2 or 4 events.

Remote outdoor sensing capability for added flexibility.
-
System mode heating and cooling lockout.
-

Remote discharge air sensor input for monitoring and control purpose.
-
System efficiency feedback.
- Discharge high limit heating lockout.
- Discharge low limit cooling lockout.
- Minimum supply air temperature.

Remote return air sensor input that replaces internal on board sensor.

Password protected configuration menu and lockable keypads for security.

Two configurable digital input for added flexibility. The input can be configured as the
following:
 None: No function will be associated with the input.
 Service: a backlit flashing Service alarm will be displayed on the Terminal
Equipment Controller LCD screen when the input is energized. It can be tied in
to the AC unit control card, which provides an alarm in case of malfunction.

Equipment Controller LCD screen when the input is energized. It can be tied to a
differential pressure switch that monitors filters.
 RemNSB: remote NSB timer clock input. Will disable the internal scheduling of
the Terminal Equipment Controller. The scheduling will now be set as per the
digital input. The menu part related to scheduling is disabled and no longer
accessible. It provides low cost setback operation via occupancy sensor or from
a dry contact.

manual remote momentarily closed contact. When configured in this mode, the
input operates in a toggle mode.
 With this function enabled it is now possible to toggle between unoccupied &
occupied setpoints for the amount of time set by parameter (TOccTime)
temporary occupancy time.

Automatic smart fan operation saves energy during unoccupied periods.

Non volatile EEPROM memory prevents loss of parameters during power shortage.

Configurable SPST output relay on scheduling models for lighting, exhaust fan or
fresh air control.

6 hour typical reserve time for clock in case of power loss.
