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 pump switching

•Automatic summer/ winter time change

•Individually configurable reduction times and holiday operation for heating circuits and hot-water

•Cascade modulating heating appliance

•Cascade switching heating appliance

•Bivalence regulator

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 (F8-T-Collector). The heat pump manager calculates the modula-

tion depth in % as a function of the difference between the current flow temperature and the target temperature. The modulation depth reflects the system's target output in %, for example the heat output made necessary by the current outdoor temperature.

The modulation depth is converted to a 0-10 V signal, whereby the outdoor unit of the heat pump is controlled..

REMKO HEAT PUMP MANAGER

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.

Target supply temperature in °C

Outdoor temperature in °C

Cooling

For the use of the cooling mode, the heat pump manager must be switched to "Cooling" mode (release of cooling mode). In addition, the basic parameters of cooling mode must be set to

"ON" and at least one of the two heating circuits must be switched to active for the cooling. The heat pump has a suitable cooling reservoir for the heating/cooling circuits through a cold water storage tank. This must take place with the hydraulic integration through a cold water storage tank (see hydraulic diagram).

Two-pipe system (combined heating/cooling circuit)

As a basic rule, it is possible to use the same circuit for both heating and cooling. In this case a suitable distribution system and a suitable single room controller must be present for cooling mode. One example of this is fan convectors. Cooling through floor heating or another surface system is possible. However, the cooling effect is lower, because no dehumidification of the room air can or may take place. In these situations the cooling return target temperature must be set high enough that the temperature cannot be expected to fall below dew point (see Specialist Cooling mode T-RL Cooling)

! ATTENTION

With the use of surface cooling, the cooling return target temperature must be set above the dew point (approx. 15 °C).

Four-pipe system (separate heating and cooling circuits)

The heat pump has an output for the connection of a cooling circuit pump and an output for the connection of a "cooling" switching valve. In the process, a separate cooling circuit can be created. With the use of fan

convectors, therefore, only cooling can take place in the summer.

Control algorithm

The control sensor for the cooling is the return sensor F17.

A command/release of the cooling can only take place from the heating circuit which is activated for the cooling. This can be both weather-controlled and room- temperature-controlled or can take place with a combination of these two types of regulation.

Weather-controlled release of cooling mode:

Cooling mode is started when the temperature falls below the target outside temperature (see User

Heating circuit 1/2 T-external Cooling). If the current outside temperature falls more than 1K below this target value, the cooling function is stopped.

NOTE

You achieve the best cooling effect with fan convectors

see REMKO supplier assortment KWD-S, WLT-S and KWK. With these devices the air in the room is cooled, rotated and dehumidified. It should be noted that the pipes of the cooling circuit must have water-vapour-tight insulation because of the additional dehumidifying performance!

Room-temperature-controlled release of cooling mode:

The room-temperature-controlled release of the cooling is only possible with a digital remote control. Cooling mode is started when the temperature falls below the target room temperature (see User Heating circuit 1/2 T-room Cooling). If the current room temperature falls more than 2K below this set value, the cooling function is stopped.

Combined release:

If weather-controlled and room- temperature-controlled cooling are activated, both release conditions must be fulfilled to start the cooling function.

Power level of the heat pump in cooling mode:

If the temperature at sensor F17 is not more than 2K warmer than the cooling return target temperature, the heat pump runs in cooling mode at a set power of 50% (5 V-signal or power level 4). With

a greater cooling load the heat pump switches to power level 7 (10 V signal or maximum power). For this purpose, sensor F17 must be at least 2K warmer than the cooling return target temperature. If this is reached at a later time, the heat pump switches back to 50% power and then switches off once the sensor F17 has become more than 2K colder than the cooling return target temperature (see Specialist Cooling Mode T-RL cooling).

If a hot water requirement arises, the cooling is interrupted for the duration of the hot water heating. However, the cooling circuit continues to operate through the cooling water storage tank.

Installation

OK

■Determine which system diagram is to be used (see the hydraulic diagram in the appendix).

■If the System 1 schematic is applicable, you need only press the F-button next to End . Should a different system schematic be selected, press the F-button next to OK to begin installation.

■The configuration in the installation level for the selected hydraulics has to be completely programmed with

the parameters that go with it (see the hydraulic schematic in the heat-pump manager handbook).

■The system has to be matched to the customer's personal values (e.g. heating curve).

■The brief instructions supplied give an overview of how to set the most important values.

■After configuration, the system is to be run-in and the measured values are to be recorded in the commissioning report.

NOTE

Check the setting of Min. T-WW WE, idle time for accuracy. (see note P. 35).

NOTE

The commissioning and programming of the heat-pump manager may only be carried out by a mechanic authorised by REMKO.

NOTE

During commissioning, only

a typical heat-manager default setting can be carried out. Individual settings must be optimised for construction materials and the practices of various users. Especially during the first heating period.

Description

Setting the desired room temperature during holiday reduction (time away) (see Time-Date holiday start / end).

Setting the desired room temperature in cooling mode for the selected heating circuit.

The cooling operation is activated if the temperature set here is exceeded and ends if this temperature is undercut by 2K. Only in connection with a remote control. With the value "----", the cooling operation is independent of the room temperature.

Furthermore, the cooling operation must be enabled by T-external cooling.

The cooling operation is enabled and activated if the outdoor temperature exceeds the value set here and ends if this temperature is undercut by 1K.

These functions are only activated after the mode HKP in the specialist menu has been programmed to heating threshold.

Setting the heating threshold.

If the outdoor temperature measured and determined by the controller exceeds the heating threshold set here, the heating will lock, the pumps shut off and the mixers close.

The heating will be enabled again if the outdoor temperature undercuts the set heating threshold by 1K.

•Heating threshold day (operates during heating periods).

•Heating threshold night (operates during reduction periods).

At "----", the heating threshold is deactivated and the circulation pump will be switched in accordance with the standard function.

The curve's slope indicates by how many degrees the supply temperature will change if the outdoor temperature rises or falls by 1°C.

If during cold outdoor temperatures the room temperature is too low (too high), the heating curve must be raised (lowered).

If during high outdoor temperatures the room temperature is too low, the room temperature must be corrected by means of the room target temperature (parallel adjustment of the heating curve).

At "0.00", room regulation is active.

Changing the heating curve 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.

This function is only active once the HK function was programmed to T-feed const in the specialist menu.

Setting the desired supply temperature with which the selected heating circuit is operated during the heating period.

This function is only active once the HK function was programmed to T-feed const in the specialist menu.

Setting the desired supply temperature with which the selected heating circuit is operated during the reduction period.

This function is only activated with the analogue remote control (FBR-2).

The WE temperature is increased in the amount of the value set here if the desired room temperature (T-room target) is undercut by 1K (room sensor impact).

Automatic regulation of the heating curve (Heating curve adaptation).

Start-up requirements:

•Outdoor temperature < 8°C

•Operating mode is automatic 1/2

•Duration of the reduction phase at least 6 hours

The current room temperature is measured at the beginning of the reduction period. This temperature is applied in

the following 4 hours as the target value for the room regulation. The heating curve is calculated from the values captured in this time period by the regulator for the supply and outdoor temperatures.

The setting remains on until the adaptation has been completed successfully and was not interrupted (e.g. by a demand for hot water from an external heating circuit).

The controller's water heating and the warm up optimisation are blocked during the adaptation.

Automatic bringing forward of the heating period start (warm up optimisation).

Depending on the weather (T-outside) or the current room temperature (T-room, only possible with the attachment of the analogue room device (FBR-2)), heating is started up early enough so that at the beginning of the set heating period, the temperature in the living area (see time programme heating circuit 1/2 prog 1/2) just reaches the set room target temperature (T-room target).The warm up optimisation is only carried out if the reduction time for the heating circuit is at least 6 hours.

Automatic optimisation of the switch-on time of the heat pump at the end of the set heating period.

The heat pump is no longer started if it is not already in operation for the duration of time set here prior to the end of the heating period (only for the last heating period) (see time programme heating circuit 1/2 prog 1/2). (This prevents short-term warming up of the heat pump at the end of the heating period).
