HKM3 heating circuit extension module
The HKM3 heating circuit module enables the control of an additional heating circuit. The controller connected can be extended by a complete weather-compensated heating circuit by connecting the HKM3 via the VBus®.
The HKM3 is equipped with 6 sensor inputs, one of which can be used for the optional RTA11-M remote control. For the connection of a mixing valve and a heating circuit pump, 3 semiconductor relays are available, as well as one potential-free relay for afterheating demand.
In combination with the controller connected, the HKM3 not only controls the basic functions of the heating circuit and the DHW priority, it also has an antifreeze function and a blocking protection for the heating circuit pump.
- Weather-compensated control of a heating circuit with timer
- Up to 3 HKM3 can be connected to a DeltaSol® E controller
- Mixer control, antifreeze function, DHW priority function
- Blocking protection of the heating circuit pump
- Remote control possible (optional)
EM extension module
The EM extension module provides 5 additional
relays and 6 additional sensor inputs for the RESOL
DeltaSol® MX controller.
Up to 5 extension modules can be connected to
the MX via the VBus®, so that a total of up to 39
outputs and 45 inputs can be made available for the
control logic. The extension modules themselves
do not require any adjustments, they are simply connected and assigned to the controller. The
inputs and outputs of the registered modules will
then be available for all functions of the controller.
With 5 extension modules and its 2 internal heating
circuits, for example, the DeltaSol® MX can
manage no less than 7 heating circuits complete
with individual room thermostats.
- 7-segment LC display
- Function control
- Slide switch 0 Auto I
- Usable for all optional functions of the DeltaSol® MX and BX Plus
- Easy to install, configurable over the controller menu
Remote control RTA11-M
The remote control RTA11-M is designed for connection
to the HKM3 and DeltaSol® e and allows a comfortable
adjustment of the controllers heating curve. Increasing the
setting causes an increase in flow temperature, a fall causes a
decrease. The remote control additionally allows the functions
“heating circuit off” and “maximise flow temperature”.
Heat conductive paste
For installation of sensors (as flatscrew or pipe sensor) into the immersion sleeves, the heat conductive paste has to be used for a good heat transfer.
Auxiliary relay
Auxiliary relay for separation of different electric circuits. Switching
capacity 16 A, 240 V~, potential-free switch-on and switch-off
contacts. The auxiliary relays can only be used for mounting into
patch panels. In the case of wall mounting, please use the housing
HRG2, appropriate for up to two auxiliary relays.
