WATCHMAN CONTROL
The WATCHMAN is an optional
intermediate remote control. It permits the
following function selections;
SYSTEM OFF- In this position all internal
and external controls are disabled.
FAN OFF- Ventilation fan is off, cold
exhaust port is closed, external devices are
active.
FAN SPEED- Low, Medium or HIGH can
be selected.
INTERMITTENT- In this mode the
ventilation fan will run at low speed for 20
minutes and turn off for 40 minutes. This
cycle will continue until cancelled. External
devices are active.
AUTO/OFF-In this mode the ventilation
fan remains off until activated by either the
internal dehumidistat or an external control
such as a touch pad or dehumidistat.
RELATIVE HUMIDITY- By rotating the
control dial you can select desired levels of
indoor humidity. Humidity reduction will
only occur during the heating season. Should
the set point be below the indoor relative
humidity the HRV will automatically switch
to high speed. Multiple controls may be
connected to the HRV. Typically, connection
leads would be distributed from a central
location and connected at the HRV with
a single 18/2 lead. Maximum number of
Watchman or Sentinel controls per HRV is
four (4) with a total of 1600 lineal ft. of 18/2
thermostat wire.
