Off
(2%/
UG
) –
second sequence where the valve opening calculated by the preheat
begins to decrease at the rate given by the
Off
parameter while enabling PID control of
the valve opening based on the required temperature
.
The actual valve opening
corresponds to the bigger of the two.
CompenssationSpeed
(
No
/
Yes
/
Only
)
– selection of preheating and fan speed
compensation combinations based on supply air temperature. The individual items have
the following meanings:
No
– no speed compensation is applied during preheating.
Yes
– speed compensation is active at the same time as preheating.
Only
– only speed compensation is active instead of preheating.
PumpOn
(
Normally
/
OnLowTout
/
Regime
/
Always
) – pump switched on outside of standard
operation. The individual items have the following meanings:
Normal
– pump turns on in the heating regime only when a valve is requested to
open.
OnLowTout
– pump turns on if the outside temperature is below 1°C, regardless of
the unit status.
Regime
– pump will turn on if
TemperatureRegulation
switches to the
Heat
state.
Always
– pump is permanently switched on in the heating regime.
PumpSpin
(
No
/
Yes
) –
this parameter enables the pump to spin down once a week to prevent
the pump from stalling.
InSummer
(
Block
/
Enable
)
– allows the water heating to be turned off in the summertime,
thus limiting the use of the hot water source if it is only for the HVAC unit.
CoolingProtection
–
protection of the heat exchanger when the cooler is placed in front of the
water heating exchanger. A preheating temperature sensor placed in front of the water
heating exchanger is a prerequisite to control the required heating output. Up to 8
temperature points of the heating performance curve corresponding to the preheating
temperature can be set.
OffProtection
–
protection of the water heating exchanger when the unit is switched off.
Exchanger protection when the heat exchanger is placed in front of the water heating
exchanger. Similar function to
CoolingProtection
, but based on the outdoor temperature.
