ED - Electrical heating
Description
ED1 - Regulation electricity
If an electrical preheater or an electrical reheater is installed, it
may be necessary to adjust the regulation time.
ED2 - Preheating tempeature
Setpoint temperature for frost protection preheater - see menu
EC1 for reference temperature sensor
ED3 - Preheat PI P
P-band for the PI controller for the electrical modulating
preheater. The P-band controls the amplification of the controller
following a deviation from the set point (speeder)
ED4 - Preheat PI I
I-band for the PI controller for the electrical modulating preheater.
The function controls how quickly the controller adapts to a
deviation of the set point (brake).
ED5 - Preheat Reg
The Preheat Cycle function works, as follows: E.g. necessary
output 50% and cycle = 60 sec means that the controller will
switch the preheater on for 30 sec and off for 30 sec.
Note: Please refer to your country-specific regulations on
limitations when adjusting this function. The modulating preheater
function refers to the value adjusted in set point EC1.The
preheater will try to maintain a steady freish air temperature
according to this set point.
When the modulating preheater is used, the existing fresh air
temperature sensor (T3), which is built into the ventilation unit,
can be used as reference. No extra temperature sensor is required.
ED6 - Reheat offset
Offset for reheater with reference to the set point for the
requested temperature.
E.g. requested temp = 20°C
Offset value = 2 reheater aims to maintain a supply temperature
of 18°C
ED7 - Reheat PI P
P-band for the PI controller for the electrical modulating
reheater. The P-band controls the amplification of the
controller following a deviation from the set point (speeder).
ED8 - Reheat PI I
I-band for the PI controller for the electrical modulating
preheater. The function controls how quickly the controller
adapts to a deviation of the set point (brake).
