SYSTEM SETUP
SYSTEM SWITCH SETTINGS
There are twelve, two-position slide switches located on the control panel. Set applicable switches in their proper
position for HVAC equipment configuration and control options.
ON OFF
HP HC SYSTEM
FOSSIL CONV HEAT PUMP
B O REV VALVE
ELEC GAS FAN
ZONE ALL FAN MODE
1 MIN OFF PURGE
20 MIN OFF TIME SHARE
MAJORITY COOL PRIORITY
TIME SHARE
Time Share can be used with either the Cooling Priority Mode or Majority Wins Mode. If zones being served
(heating or cooling) have not been satisfied within 20 minutes and an opposite call takes place, the system will
changeover. When that mode is satisfied or 20 minutes has gone by, the system will again changeover if an
opposite call exists.
FAN MODE
When the Fan Mode slide switch is set in the ALL position and at least one zone thermostat is set in the fan ON
mode, all zone dampers will open for ventilation air between equipment calls. When the Fan Mode slide switch is
set in the ZONE position, only those zone thermostats set in the fan ON mode will have their dampers open for
ventilation air between equipment calls.
CAPACITY CONTROL SETTINGS
The three Capacity Control slide switches have a numerical value of 2, 3 and 4. Any switch or combination of
switches set in the ON position establishes the Capacity Control value. This value equals the minimum number of
zones that must be calling in the same mode before a second stage
can be
energized. Capacity Control only
allows for the upstaging to occur; it still requires a second stage call from the thermostat or Stage Timer to actually
initiate the second stage of the equipment. It is recommended that the Capacity Control value equal no more than
50% of the total number of zones. This feature works with multi-stage and single-stage thermostats. The Stage
Timer must be ON when single-stage thermostats are used with multi-stage equipment.
STAGE TIMER
The Stage Timer switch is located below the Capacity Control switches. When the switch is set in the ON
position, the adjustable Stage Timer is activated. This feature allows for the use of single-stage zone
thermostats with multi-stage and heat pump equipment. The Stage Timer can be set from 5 to 20
minute upstaging. (Typically set at 10 minutes)
ADJUSTABLE LIMITS
High Limit (Z-600-DAS Sensor) - Set at 170° for conventional heating systems and dual fuel applications. Set at
120° for heat pump. Allows fan to run but shuts off or down-stages equipment to prevent overheating.
Low Limit (Z-600-DAS Sensor) - Adjustable from 40° to 58° for both heat pump systems and conventional air con-
ditioning. Allows fan to run but shuts off or down-stages equipment to prevent the coil from freezing.
Low BP (Z-600-OTS Sensor) - Set balance point to prevent heat pump operation when outdoor temperature
falls below setpoint. (Typically set at 35° F)
High BP (Z-600-OTS Sensor) - Set balance point to prevent fossil fuel heat operation when outdoor temperature
rises above setpoint. (Typically set at 55° F)
