Function

It is the function of the Multitalent heat pump manager to operate and effectively manage the entire warm water pump system including any additionally installed heating appliances. The multitude of functions provided by the heat pump manager must be conﬁgured in accordance with the existing heating system. This manual provides both installation instructions and a overview of what actually lies behind the heat pump manager's conﬁguration parameters. The following functions are displayed in the heat pump manager:

• Heat pump operation

• Weather managed regulation

of a direct heating circuit and a mixing circuit (e.g.: ﬂoor heating)

• Hot-water heating

• Cooling

• Solar function

• Demand oriented circulation

Control principles

Using an outdoor temperature sensor and the selected heating curve, the heat pump manager continuously establishes the target ﬂow temperature and compares this temperature with the current system ﬂow temperature (T collection sensor F8). The heat pump manager calculates the modula-

Heating curves

The heating curve is used for the purpose of assigning the building and appropriate target supply temperature in accordance with the outdoor temperature. The heating curves 0.2 to 0.8 have their base point at 20°C and are intended for surface heating. The heating

curves 1 to 3 have their base point at 27°C are therefore appropriate for radiator heating (steel radiators). The heating curve is easiest to set at outdoor temperatures below 5 °C. Changing the heating curve setting must be carried out in small steps and in larger time

intervals (at least 5 to 6 hours), because the system must ﬁrst adjust to the new values after every change in the heating curve.

Return cooling can only take place if the temperature of

the tank rises above the collector temperature at least by

the amount of the return cooling difference set here + 3K

hysteresis.

Setting the safety temperature limits.

If a tank has a top mounted sensor, the maximum

temperature set here will be monitored by this sensor.

If this sensor is not mounted, the maximum tank

temperature will be monitored by the bottom mounted

sensor (In this case the layer arrangement in the tank must

be taken into account).

The charge pumps lock if the heating tank temperature rises

above the safety limit set here (system protection).

The pumps are enabled again if the heating tank

temperature falls below the temperature

REMKO Heat Pump Manager

System selection

12 basic hydraulic conﬁgurations are provided in the heat pump manager which can be pulled up with the system selection and applied in the controller. Pulled up with the system selection and applied in the controller.

The system selection was decided in accordance with the following criteria:

1. by type of heat pump

- only heating series: CMF 80, CMF 140

- Heating/cooling series: CMF 90/150/120/160,

CMT 100/150/120/160

CMF 120/160

System selection

Functions

Basic hydraulics for the functions “Heating and hot water”, single energy-source mode, 1 supplemental electric heating, bivalence point -5°C

2. by operating mode

- single energy source operation (supplemental heating is a supplemental electric heater)

- bivalent mode (supplemental

heating is a boiler)

3. by special case

- integration of solar systems

- integration of solid fuel boilers

The following pages show a selection of these basic hydraulic conﬁgurations with the corresponding basic programming list.

In any case, during commissioning, assign one of the basic hydraulic conﬁgurations via the menu item system selection to the “On-sitesystem”. Take special care that the system you select is as near as possible to system installed onsite. The location of the sensors is especially important. Please orient yourself on the system diagram for the selected system.

not for heat pumps with heating meters

Heating/cooling version, single energy-source mode, 1 supplemental electric heating, Bivalence point -5°C

Heating/cooling version, single energy-source mode, 1 supplemental electric heating, solar system, bivalence point -5°C

not for heat pumps with heating meters

NOTE

Heating circuit 2 and hot water are recognised by the connected sensor. The relevant menus are hidden if no sensor is connected.

The systems 2, 3, 4, 5, 8 and 9 were programmed for the equipment type CMF 80/140 and cannot therefore be selected for heat pumps with heating meters!

NOTE

Please also note the connection diagrams or the electrical circuit diagrams for the installed heat pump. These are found in the respective installation manual.

Troubleshooting and customer service

Fault numbers appear in the controller display if your heating system malfunctions.

There are three types of reports:

1. Info: Information and descriptions "Display" heat generation.

2. W 051 Warning: Maintenance required "Maintenance"

3. Info 055 Information: Heat pump lock "WP lock"

The meanings of the displayed error codes can be taken from the table on the next page. The system should be restarted after the fault has been corrected => RESET.

RESET : Brief shut-off or the equipment (mains switch). Controller starts again, conﬁgures itself again and continues to work with the already set values (fault messages for defective sensors may no longer appear => corresponding functions may be deactivated).

General troubleshooting information

If the system does not operate correctly, ﬁrst check the cabling in the controller and controller components.

Sensor

At the level "General/ Service/ Sensor test", all sensors can be checked. All of the connected sensors have to appear here with plausible measured values.

Actuators (mixers, pumps => only with code number)

At the level "General/ Service/ Sensor test", all actuators can be checked. All relays can be switched individually at this level. This enables the correct connection of these components (e.g. direction of rotation of the mixers) to be easily checked.

BUS - connection

In controllers with connection to mixers => display of the communication icon in the standard display (depending on the design " " or "v") or under "Service/communication MM 1“ WE controller => display of the outdoor and WE temperature (see "Displays/ system") or in the boiler control if connected to the controller => display of the room temperature and hiding of the current room target temperature "----" (see "Displays/ heating circuit") in the mixer expansion controller if connected to the boiler controller => display of the outdoor and WE temperature (see "Displays/system") controller => display of the room temperature and the hiding of the current room target temperature "----" (see Displays/heating circuit")

RESET of settings: Overwriting settings with standard values can be carried out separately at the "Service level" for the "user" and "specialist" parameters and the "time programme" respectively.

REMKO Heat Pump Manager

The equipment and components are manufactured using state-of-the-art production methods and tested several times to verify their correct function. If malfunctions should occur, please check the functions as detailed in the list below. Please inform your dealer if the unit is still not working correctly after all the functional checks have been performed!

Bus wiring and sensor wiring must be separated spatially from mains wiring.

Check poles

There must be at least 8V DC between the BUS plug's "+" and "-" terminals [terminals 18+19]. If too little voltage is measured, an external supply must be installed.

Type of pump switching at the specialist level heating circuit

Check operating mode => standard. Check time and heating programme => heating period Check pump switching => type of pump switching Standard => outdoor temperature > room target temperature? Heating limits => outdoor temperature > valid heating limit? Room controller => room temperature > target temperature + 1K Additional tests via the controller's relay test function.

Fault indicated by code

Only the fault with the highest priority is displayed.

- The message "Fault" appears in the standard display and the fault number in the favourites line. The fault can be rotated out of view and rotated back into view in the display => see favourites.

- The current fault can always be found at the end of the display level "Display".
