2.2 About the controller
The weather controlled Heat Circuit Controller HCC 3 facilitates efficient use
and function control of your heating system. The device is impressive
most of all for its functionality and simple, almost self-explanatory operation.
For each step in the input process the individual entry keys are assigned
to appropriate functions and explained. The controller menu contains
headwords for the measured values and settings, as well as help texts or
clearly-structured graphics.
Important characteristics of the HCC3:
- Depiction of graphics and texts in a lighted display
- Simple viewing of the current measurement values
- Statistics and monitoring of the system by means of statistical graphics, etc.
- Extensive setting menus with explanations
- Menu block can be activated to prevent unintentional setting changes
- Resetting to previously selected values or factory settings

showing the respective hydraulic systems, and do not claim to be
complete. The controller does not replace safety devices
under any circumstances. Depending on the specific application, additional
system components and safety components may be mandatory, such
as check valves, non-return valves, safety temperature limiters, scalding
protectors, etc., and must therefore be provided.

Caution
Install the controller only in dry areas and under the ambient conditions
described under 2.1 „Specifications“. Carry out the following steps 1-8.
Fig.3.1.1
Fig.3.1.2
1. Unscrew cover screw completely
2. Carefully pull upper part of housing
from lower part.
3. Set upper part of housing aside,
being sure not to touch the electronics
when doing so.
4. Hold the lower part of the housing
up to the selected position
and mark the 3 mounting holes.
Make sure that the wall surface
is as even as possible so that
the housing does not become
distorted when it is screwed on.
5. Using a drill and size 6 bit, drill 3
holes at the points marked on the
wall and push in the plugs.
6. Insert the upper screw and screw
it in slightly.
7. Fit the upper part of the housing
and insert the other two screws.
8. Align the housing and tighten the
three screws.
Caution
For panel installation, a
special installation set is
available as an accessory.

3.2 Electrical connection
Before working on the unit, switch off the power supply and secure
it against being switched on again!
Check for the absence of power!
Electrical connections may only be made by a specialist and in
compliance with the applicable regulations. The controller may not be put
into operation if there is visible damage to the housing, e.g. cracks.
Caution
Danger
Low-voltage cables such as temperature sensor cables must be
routed separately from mains voltage cables. Feed temperature
sensor cables only into the left-hand side of the unit, and mains
voltage cables only into the right-hand side.
Caution
Fig.
3.2.1
Caution
The cables being connected to the unit must not be stripped by
more than 55mm, and the cable jacket must reach into the housing
just to the other side of the strain relief.
The customer must provide an all-pole disconnecting device, e.g.
a heating emergency switch.
1.Open controller housing (see 3.1)
2.Strip cables max. 55mm, insert, fit
the strain relief devices, strip the last
8-9 mm of the wires. (Fig.3.2.1)
3.Open the terminals using a suitable
screwdriver (Fig. 3.2.1) and make
electrical connections on the controller
(Pages 10)
4. Refit upper part of housing and
fasten with screw.
6. Switch on mains voltage and
place controller in operation
