SP11 Automatic chiller / heat pump mode changeover differential
The status change over can only take place if these necessary conditions are present at the same time,
otherwise the unit REMAINS in stand - by:
4. CF02=3 (chiller with heat pump)
5. SP09=2 is an NTC probe configured as an Dynamic/boiler function/change over set-point external
air temperature NTC temperature probe(AI type=35)
6. the regulation probe selected must not be in error conditions
AUTOMATIC CHANGE OVER REGULATOR GRAPHICS
Parameters that regulated the change over function
SP10 allows setting the change over set point. If the selection of the working mode from analogue input is
enabled, it represents the temperature value detected by the regulation probe below which the device
imposes the working in heating mode
SP11 allows setting the change over differential. If the selection of the working mode from analogue input is
enabled, it represents the temperature differential on the basis of which the device imposes the working in
cooling mode
For temperature of the external air included in the SP11 differential, it is allowed to change the working mode
from the keyboard.
NTC external air temperature regulation NTC probe > SP10+ SP11, the unit is switched-on in cooling mode.
NTC external air temperature regulation NTC probe < SP10, the unit is switched-on in heating mode.
