MAXA i-MAX 0466 - Dynamic Set-Point Control; Circulator Management (If Installed)

i-MAX Industrial inverter air/water heat pump with axial fans

7.1 DYNAMIC SET-POINT CONTROL
The controller allows change the set-point by adding a value depending on the temperature of the outdoor air sensor. This
function can be used if necessary by modify the parameter values, following the below information (it is the installer’s
responsibility to change the parameters).
b08 active = 1/not active = 0 dynamic set-point (in the case of using of the optional “Hi-T” remote control panel for climatic
compensation, b08 must be deactivated).
b09 = Maximum offset in cooling.
b10 = Maximum offset in heating.
b11 = Set of outdoor temperature in cooling.
b12 = Set of outdoor temperature in heating.
b13 = ΔT in cooling.
b14 = ΔT in heating.
For parameters setting, please see paragraph 11.4.
Set-point modification as a function of the outdoor temperature:
7.2 CIRCULATOR MANAGEMENT (IF INSTALLED)
The circulator of the pump can be set according to one of the following operation modes:
- Operation by thermo-regulator (default)
- Operation by thermo-regulator with periodic activation
- Continuous operation
The circulator will immediately switch off if:
- You have a pump (circulator) locking alarm including the manual reset flow switch alarm.
- The unit is in stand-by mode or when it’s switched off from a remote input (when it’s turned ON). The circulator turns off
always with a delay given by P02.
The circulator is always running if the antifreeze heaters are ON.
The circulator can be configured with the parameter P03 in order to make it operating independently than the compressor or
under a call for operation.
P03 = 0 for Continuous operation during heating/cooling modes(default),
P03 = 1 for operation under the thermoregulatory call
Note: Whenever the flow switch alarm is automatically reset the pump is ON even if the compressor is off.
Otherwise, the circulator remains always in operation if the antifreeze heaters are ON or when the hydraulic pump operates in
antifreeze mode. The operation in antifreeze mode starts if the water setting temperature decreases below P04 °C (default value
5°C), and stops if the water setting temperature increases above P04+P05 °C (the default value of P05 is 2,0°C).
The regulation of the circulator is linear type (see paragraph 7.2.5). To changer the parameters, please see paragraph 11.4.
