Structure and mode of action

The EQJW246F003 heating and district heating controller is used to control up to three control circuits.

Control of a primary heat exchanger or boiler with up to two mixed and one unmixed heating circuit (each weather-compensated) and control of DHW heating on the se-condary side
Weather-compensated buffer cylinder control with up to two mixed heating circuits and fresh water module
Control of two weather-compensated heating circuits and a DHW heating system with three valves on the primary side
Control of three weather-compensated heating circuits with three valves on the primary side
Applications with up to six control loops possible via optional extension modules (0440210014) (coupled via device bus)
Systems with a larger number of control loops can be realized by interconnecting controllers via a device bus.

The EQJW246F003 heating and district heating controller is customized to the specific system by setting a system code number. Additional sensors and/or functions not included in the basic system configuration are then selected by defining function blocks. The corresponding levels are accessed by selecting the switch position and then entering the code number. For the specialist personnel, configuration levels for defining function blocks are labelled „CO” and parameter levels are labelled „PA”. Data is entered and queried on the heating and district heating controller using a rotary and push button. It is supported by symbol overlays and plain text on the LC display. The rotary switch is used to set the operating modes and the main parameters of the individual circuits.

M-Bus interface
Up to three meters in accordance with EN 1434-3 can be connected for data transmission. In addition, heat meters for volume flow and/or output limitation are available for each control circuit. For control circuit HK1, different limit values can be set for the different operating states „heating control only”, „heating control with simultaneous DHW heating” and „DHW heating only”. Weather-compensated volume flow or output limitation can also be realized.

Electrical connection

DANGER
Danger to life from electric shock!

When wiring and connecting the heating and district heating controller, the VDE regulations and the regulations of the local energy supply companies must always be observed. This work must therefore be carried out by a specialist!
Terminals 33, 39, 42 and 45 allow the targeted integration of safety devices with a direct effect on the individual motor drives and pumps. If this is not required, connect a jumper from terminal 31 to terminals 33, 39, 42 and 45.
Do not connect cables carrying extra-low voltage in accordance with VDE 0100 directly.
De-energize the heating and district heating controller before working on the connections.

Instructions for laying the electrical cables

Lay 230 V supply lines and signalling lines separately and at a distance.
To increase interference immunity, maintain a minimum distance of 10 cm between the cables. This spatial separation must also be observed within an electrical enclosure.
Also lay the cables for digital signals (bus cables) and analogue signal cables (sensor cables, analogue outputs) separately and at a distance.
Use shielded cables for the analogue signals in systems with a high electromagnetic interference level.
Earth the shield on one side at the inlet or outlet of the switch cabinet, making contact over a large area. Connect the central earthing point to the PE protective conductor by the shortest route (conductor cross-section at least 10 mm²).
Equip inductivities in the switch cabinet, e.g. contactor coils, with suitable interference suppression circuits (RC elements).
Shield switch cabinet parts with high field strengths, e.g. transformers or frequency converters, with separators that have a good connection to the PE protective conductor.
Use cables with wire cross-sections according to Table 5-1 for the terminal connections.

Overvoltage protection

If signalling cables are laid outside buildings or over long distances, take suitable overvoltage protection measures. Such measures are essential for bus cables.
The shielding of signalling cables that are laid outside buildings must be current-carrying and earthed on both sides.
The surge arresters must be installed at the entry to the switch cabinet.

Connection of the heating and district heating controller

If the controller housing and rear part of the housing are not already separated: To connect the cables, open the housing by loosening the front screws at the bottom left and top right.
Break through the openings marked for the cable entry at the top, bottom or rear of the rear part of the housing and fit the enclosed grommets or suitable screw connections.
For wall mounting: Before inserting the cables into the base, support them with suitable measures, e.g. a cable duct, so that there is no strain or bending on the cables.

Connecting the drives

0-bis-10-V-control output:
Use cables with a wire cross-section of at least 0.5 mm².
Three-point/two-point control outputs:
Run cables as damp-proof cables with a core cross-section of at least 1.5 mm² to the terminals of the controller output. It is advisable to check the running direction during commissioning.

Connecting the pumps
Route all cables with a core cross-section of at least 1.5 mm² to the terminals of the heating and district heating controller in accordance with the wiring diagram.

Note
The motor drives and pumps are not automatically supplied with power by the heating and district heating controller. They can be connected to an external power supply via terminals 33, 39, 42 and 45. If the electrical supply is to be internal, a jumper must be connected from terminal 31 to terminals 33, 39, 42 and 45.
