ChangePower
(30 s)
– some manufacturers' condensing units require a power change no
more than once per time interval.
DelayOnOff
(60 s)
– Delaying the on and off time of every condensing unit will ensure that the
condensing unit compressor does not turn on too often. Combined with the minimum power
required to turn on
PowerOn
, the number of condensing unit starts during transient periods
will be reduced. The maximum number of starts of the condensing unit is 6 starts per hour.
FDP3–CoolOn
(6,25 V
) – is relevant for condensing units whose states are controlled by a
constant voltage level of 0-10V DC signal (
TypeControl
=FDP3
). The voltage according to the
technical specification at which the cooling regime of the condensing unit is switched on is
entered.
FDP3–AirOn
(4,75 V
) – is relevant for condensing units whose states are controlled by a
constant voltage level of 0-10V DC signal (
TypeControl
=FDP3
). The voltage according to the
technical specification at which the ventilation regime of the condensing unit is switched on is
entered.
FDP3–HeatOn
(3,25 V
) – is relevant for condensing units whose states are controlled by a
constant voltage level of 0-10V DC signal (
TypeControl
=FDP3
). The voltage according to the
technical specification at which the heating regime of the condensing unit is switched on is
entered.
PID–Regulation
– the default factory set values are:
TI = 300 s, KP = 5, TD = 0 s.
Cool
,
Heat
(
Normal
/
Invert
) – allow to invert the control signals of the condensing unit output.
Normal
– output signal 0% = 0 V, 100% = 10 V.
Invert
– output signal 0% = 10 V, 100% = 0 V.
ControlModulEKE
–
is important for condensing units with EKE control. Up to 8 points of the
condensing unit output curve can be set corresponding to the difference between the
required and actual temperature.
ControlModulFDP3
– is important for condensing units with FDP3 control. Up to 16 points of
the condensing unit power curve corresponding to the required temperature can be set.
Heat pump
6.12
The heat pump is a compact part of the Mandík air conditioning unit, if fitted. The heat
pump circuit with heating and cooling function can be single or double circuit. It consists of an
