E13: Floor heating temperature
Here a temperature is set, which can be used in connection with menu item E19=2 , i.e.,
the minimum temperature, at which the circulation pump for the floor heating starts. If the
temperature T8 (water tank) is less than the value set at menu point
E13
, the circulation pump
stops.
Options: 20-50 °C
Factory setting: 35 °C
E15: External start / stop control
Value of 0: The control switches to P1, mode 3, if input T10 (External start / stop) is short circuited.
When T10 is interrupted again, the controller goes back to the mode, prior to short circuiting.
This function can be used by an external hygrostat which, at high humidity, can force the system
to mode 3.
Value of 1: The control switches to P1, mode 0 (unit standby) if input T10 (External start/stop)
is short circuited. When T10 is interrupted again, the controller goes back to the mode, prior to
short circuiting. This function can be used for simple external control of the heat pump unit, e.g.,
simple start/stop control from a potential free contact.
Value of 2: PV mode. External control of the unit via variable voltage input to T10. Please see
menu points
E30
to
E32
for control details.
Input T10 requires a 0-3VDC signal. Special cables can be supplied for conversion of a 0-10 VDC
signal or a 4-20mA signal.
Options: 0-2
Factory setting: 0
E16: Minimum air flow
This value specifies the minimum air flow, which the fan should provide during operation. Please
be aware that the cooling system may be overloaded resulting in the high pressure switch alarm
if this value is set too high. The value should not be chosen higher than necessary to ensure a
minimum air flow through the evaporator.
Options: 0-100 %
Factory setting: 15 %
E17: Forced operation ON
If P1 is set to mode 3, there is a possibility that the system automatically switches to mode 1
after the number of hours set at menu point
E18 .
Value of 0: The system runs in P1 mode 3, until it is manually changed to a different step.
Value of 1: System returns to mode 1 after the number of hours set at menu point E18 .
Options: 0-1
Factory setting: 0
