4. STAT B TO W (cont.)
NOTE: Some OEMs use the B terminal as a transformer
Common and not as the heating reversing valve. These
thermostats will use the O terminal for the reversing valve
and should be wired accordingly using DIP Switch #3. The B
terminal will then be wired to the C terminal on the thermo-
stat terminal block.
5. FAN IN PRG – This switch keeps the fan running during the purge
time in order to dissipate the conditioned air into the last zone(s)
calling. Placing this switch to ON prevents the fan from turning off
from the fan control in the HVAC Unit during the purge mode and
coming back on moments later if another call is waiting. In OFF
the fan will be controlled by HVAC Fan controls. This is desirable
in residential applications to prevent cold drafts after heating by
having the switch OFF.
6. CNTL 1 – EMERGENCY HEAT – This switch can be used to place
all zones into the Emergency Heat mode. This switch would be
used when single stage thermostats are used. NOTE: There is no
indication on the panel to show this switch is ON.
7. CNTL 2 – Future Use.
8. CNTL 3 – Future Use.
One of the many features of the DIP switches is if at anytime the
equipment is changed from single stage to heat pump or vice versa
the thermostats do not need to be changed with the equipment
change. Changing the DIP switch settings is all that is needed.
WIRING
The CZ-4 is very simple to wire and requires only a minimum number
of connections. The CZ-4 terminal blocks are screwless and all wires
can easily be pushed into their respective terminal by depressing
the button for each point and releasing once the wire is seated. To
remove the wire, just press its button again and remove the wire.
Zone Dampers – The CZ-4 can power any 24VAC damper, either
2 wire or 3 wire. See specific wiring instructions with the damper or
inside panel cover.
Zone Thermostats – The thermostats wiring will be for single stage
(Y-G-R-W-C) or Heat Pump (Y-G-R-E-C and O or B). This wiring is
shown on diagrams 1 for single stage and 3 for heat pumps.
Equipment – The HVAC equipment will follow wiring diagram 2 for
single and two stage systems or 4 for heat pump systems.

STAGE TIMER
The CZ-4 has a built-in stage timer that eliminates the need and
added cost of using two stage thermostats. On a call for either heat-
ing or cooling the timer begins. A minimum of 5 minutes, adjustable to
a maximum of 23 minutes, can be set in order to activate the W2 or
Y2 outputs after the first stage call.
The Stage Timer is marked 0 through 9 and each increment is indent-
ed as the dial is rotated. A minimum 5 minutes is set when the dial is
set to 0. To calculate the stage timing the dial setting is multiplied by 2
and added to the base of 5 minutes. Example: Dial setting is 3 x 2 = 6
+ 5 = 11 Minutes for the Stage Timer.
