SHP M ECO Heat pump air/water inverters with axial fans Speed P06/P09 ΔT [°C] The circulator is at maximum speed in DHW production. Note: If the parameter r33 > 0, then the circulator can be running on call even to activate the system and/or sanitary heater, see par.10.8. 7.6 SYSTEM VENTING Function used to vent the system, with the circulator at maximum speed.
SHP M ECO Heat pump air/water inverters with axial fans Switching from utility water to domestic hot water, the working probe changes from “water outlet probe” to “DHW tank probe”. Switching from winter mode to sanitary mode, the compressor does not switch off and is brought to the maximum frequency established by the controller, whereas switching from summer mode to domestic hot water, the compressor is switched off and waits a safety time.

SHP M ECO Heat pump air/water inverters with axial fans I/O resource - Parameter Value Function Closed contact -> active DHW call. ID9 can be activted via H53 Open contact -> inactive DHW call. The poles of the digital input can be swapped by setting H76=1 The SAN setpoint of the heat pump is not considered, the designer is in charge of managing this setpoint, taking into account domestic hot water protection and configuration of the entire system.
Page 20
SHP M ECO Heat pump air/water inverters with axial fans If domestic hot water production lasts longer than r16 (minutes) or if the machine blocks due to triggering of an alarm, the heater switches on. It switches off when the unit finishes domestic hot water production (also taking into account an offset on the setpoint with parameter r31, as explained in Paragraph 10.11.1).

This protection is guaranteed even with the machine Off. 12.4.3 Collector overtemperature alarm If the collector probe exceeds the value of parameter S12, there is an alarm condition E10 which blocks the solar circulator. The hysteresis to return from the alarm condition is given by parameter S08.
