UMHPI Industrial inverter air/water heat pumps with axial fans Heating SETPOINT ADJUSTMENT FROM 0-10V INPUT Another type of setting that allows to change the setpoint by adding (or subtracting) a value in function of the 0-10V analogue input (if enabled). To enable the function, you must set the H21 parameter to be 40, and change the values of the parameter b15 (range 0-10), taking into account that: if the input is at 0 volts you will have the actual set point: set point (Coo/Hea) - b15/2.
UMHPI Industrial inverter air/water heat pumps with axial fans The adjustment of the circulator is linear (see Paragraph 7.3.5). Please see paragraph 11.6 for changing the parameters. 7.3.1 OPERATION BY MEAN OF THE THERMOREGULATOR (Default) During this operating mode (P03=1, default), the thermo-regulator actuates the circulator; after a time delay of P01 seconds from startup of the circulator pump, the compressor also will turn on.
UMHPI Industrial inverter air/water heat pumps with axial fans • P10: Delta modulating pump (°C) − In cooling mode: ΔT= [Water inlet temperature] – [Water outlet temperature] − In heating mode: ΔT = [Water outlet temperature] – [Water inlet temperature] Example in cooling: If the difference in temperature between water inlet and outlet is greater than P09 + P10, the pump will run at maximum speed.
UMHPI Industrial inverter air/water heat pumps with axial fans − The requests of capacity decreasing will be done by selecting among the whole running compressors at the nominal capacity. The selection will consider the one with higher hours number of operation.
UMHPI Industrial inverter air/water heat pumps with axial fans • HzMaxReg = Maximum working frequency of the compressor in cooling mode based on the limitations described in the previous paragraphs The following curve shows the adjustment without integral component (b07 = 0) During the start-up, the compressor initiates at the minimum speed C12 or C14 (as defined from the envelope) for a given time period equal to C11 and then changes its speed to C13 for a period equal to C51-C11.
UMHPI Industrial inverter air/water heat pumps with axial fans 7.5.3 FAN SPEED CONTROL IN HEATING MODE The fan speed control in heating mode follows the diagram shown below, where: F10 = Delta cut-off of the fan in cooling/heating mode F11 = Cut-off hysteresis in cooling/heating mode...
UMHPI Industrial inverter air/water heat pumps with axial fans ALARM NOTIFICATION You can configure a digital output for alarm notification function. In order to enable such function, you should enter into the parameters as following: press PRGPSSPRG(then insert the service password) PRG PAr PRG CnF See paragraph 11.2.
- Or after a period of time equal to b06 seconds (default 45 seconds). For each UMHPI unit (except the last unit of the cascade), you must implement a relay (not included), controlled by the output 230VAC NO1 and N located on the terminal block, that can enable through its free contacts COM and NO the ADI2-ADI2 digital...
UMHPI Industrial inverter air/water heat pumps with axial fans NOTE: turning off the unit remotely (onoff-onoff terminals), or by the on board keyboard, or by a remote keyboard does not affect the DHW operating mode. Once the H10 parameter is set to be 1, the unit switches to DHW priority as soon as powered. The on board display shows the temperature measured by the sensor placed inside the DHW water tank.
This function is recommended in the case of utilization of two or more UMHPI units installed in cascade configuration and linked through a hydronic connection to the same accumulation tank of domestic hot water;...
In case of using a 3-way changeover valve with 2 contacts for power supply (with spring return), [terminals: NO1 – N] For the models UMHPI 260, this function can be activated only with the presence of the optional “GI” module. 7.15 PLANT CIRCUIT REMOTE SENSOR...
