Z-200-HC Installation and Operation Instructions
1 Heat / 1 Cool - Auto Changeover - First Call Priority - Time Share
High and Low Limit Protection:
Sequence of Operation:
Fan Mode:
The Z-200-DAS Discharge Air Sensor should be
mounted on the discharge air plenum of the
HVAC unit and wired to the DAS terminals on
the panel. If the heating temperature rises above
170° F or if the cooling temperature falls below
45° F, the sensor will cycle the equipment, while
the fan continues to run. When the system goes
out on low limit a 3 minute time delay is
activated before cooling is allowed to energize
(providing the discharge air temperature has
risen above 45° F). LIMIT LED blinks when high
or low limit is reached.
The Green Zone™ Z-200-HC is a residential /
light commercial zone control system that allows
a single HVAC unit to have up to two separate
zones. Each zone is controlled by its own space
thermostat and motorized zone damper. If a
zone thermostat calls for heating or cooling, the
zone not calling will have its damper powered
closed, and the zone calling will have its damper
opened. The heating or cooling equipment will
also be brought on at the same time. When the
zone calling is satisfied, the heating or cooling
equipment turns off. If one zone calls for heating
and another zone calls for cooling, the first zone
to call receives priority. When the first call is
satisfied, the system will changeover and take
care of the opposite call. If a zone being served
(heating or cooling) has not been satisfied within
20 minutes and an opposite call takes place, the
system will changeover. When the zone is
satisfied or 20 minutes has gone by, the system
will again changeover if an opposite call exists.
This is referred to as Auto Changeover - First
Call Priority - Time Share. In the event of a tie,
cooling will receive priority.
Zone ventilation is established by the individual
zone thermostat fan setting. Any thermostat set
in the fan AUTO mode will not receive ventilation
air when no equipment calls are taking place.
Any thermostat set in the fan ON mode will
receive ventilation air whenever there are no
heating or cooling calls taking place.
Installation Notes:
To install the panel, first remove the cover by
pulling straight out and slide the PC board from
its base. Screw the base to a flat surface next to
or on the HVAC unit. The PC board should be
reinstalled by centering it over the base and
pushing firmly.
The control panel requires a separate 24 volt
transformer.
No special wire is required.
Thermostats and motorized zone dampers may
be located up to 300 feet from the control panel
when using 18 gauge thermostat wire.
The 2 Amp fuse marked HVAC Equipment
protects the relay contacts.
The 4 Amp fuse marked Zone System protects
the printed circuit board.
Connect only 24 Vac to Control Panel.
Zone dampers are powered closed /
spring return open.

A 40 VA transformer will power the panel and up to
four (4) dampers. A 75 VA transformer will power
the panel and up to six (6) dampers. If more than
three (3) dampers for an individual zone are
required, a RY-1-HB relay should be used with an
additional properly-sized transformer (10 VA per
damper).
