GasHeating
(
No
/
Modulation
/1st/2st
)
– determines how the gas heating is controlled:
Modulation
– installed gas burner is modulating.
1st
– installed gas burner is a single stage one.
2st
– installed gas burner is a two-stage one.
DamperAtHeatExchanger
(
No
/
Temperature
/
Press
)
– bypass damper configuration of the
gas exchanger:
Temperature
– gas exchanger includes an exchange damper that is controlled based
on the temperature of the flue gas.
Press
– gas exchanger includes an exchanger damper that is controlled based on the
pressure at the exchanger.
WaterCooling
(
No
/
Separate
/
WithHeat
/
2WithHeat
)
– determines how the gas water cooling is
controlled:
Separate
– AC unit has a separate water cooling exchanger.
WithHeat
– AC unit has a common water heat exchanger for cooling and heating. The
antifreeze thermostat is blocked in the cooling regime.
2WithHeat
– AC unit has a common water heat exchanger for cooling and heating. By
default, cooling is enabled by an open external contact (

), which signals cooling water readiness. The
antifreeze thermostat is blocked in the cooling regime.

heating and cooling functions or up to 6
condensing units with only
C
cooling function.
TypeControl
(
Modulation
/ANL2WIRE/FDP3/EKEQFCB/PAC–IF
)
– types of control modules
of the individual manufacturers of condensing units are selected here.
Modulation
– 0-10V output control signal corresponds to the required 0-100%
output in both heating and cooling regimes. The switching of the Cooling/Heating
regimes is done by voltage-free contacts.
ANL2WIRE
– is designed for controlling some types of Fujitsu condensing units and
VRF-kits with 0-10V voltage. At 0V voltage the condensing unit is switched off. At
voltage of 0.6 to 10V, the unit is switched on the voltage level corresponds to the
