1 Installation
1.1 Mounting
The RQ DHW controller is already integrated in the
Regumaq DHW exchange module. If the controller is
to be installed outside of the DHW exchange mod-
ule, please mind the following instructions.
The controller must additionally be supplied from a
double pole switch with contact gap of at least 3mm.
Please pay attention to separate routing of sensor
cables and mains cables.
WARNING! Electric shock!
Upon opening the housing, live
parts are exposed!
ÎAlways disconnect the con-
troller from power supply
before opening the housing!
In order to mount the device to the wall, carry out
the following steps:
ÎUnscrew the cross-head screw from the cover
and remove it along with the cover from the
housing.
ÎMark the upper fastening point on the wall. Drill
and fasten the enclosed wall plug and screw leav-
ing the head protruding.
ÎHang the housing from the upper fastening point
and mark the lower fastening points (centres
150 mm).
ÎInsert lower wall plugs.
ÎFasten the housing to the wall with the lower
fastening screws and tighten.
ÎCarry out the electrical wiring in accordance
with the terminal allocation, see chap. 1.2.
ÎPut the cover on the housing.
ÎAttach with the cross-head screw.
1.2 Electrical connection
ATTENTION! ESD damage!
Electrostatic discharge can lead to
damage to electronic components!
ÎTake care to discharge
properly before touching
the inside of the device!To
do so, touch a grounded
surface such as a radiator
or tap!
The controller is equipped with 4 relays in total to
which loads such as pumps, valves, etc. can be con-
nected:
Relays 1 … 4 are semiconductor relays, designed for
pump speed control:
Conductor R1 … R4
Neutral conductor N (common terminal block)
Protective earth conductor PE (common terminal
block)
Note:
Connecting the device to the power supply
must always be the last step of the instal-
lation!
Note:
The minimum pump speed must be set to
100 % when non-speed-controlled devices
such as valves are connected.
Note:
Strong electromagnetic elds can impair
the function of the controller.
Make sure the controller as well as the sys-
tem are not exposed to strong electromag-
netic elds.

CommissioningAdjustmentsTroubleshooting Data communication
2 Commissioning
When the hydraulic system is lled and ready for op-
eration, connect the controller to the mains.
The controller runs an initialisation phase in which
the directional pad ashes red.
When the controller is commissioned for the rst
time or when it is reset (see page 32), it will run
a commissioning menu after the initialisation phase.
The commissioning menu leads the user through the
most important adjustment channels needed for op-
erating the system. For navigating in the commission-
ing menu, see page 8.
2.1 Step-by-step parameterisation
a. Running the commissioning menu
The commissioning menu is run after the rst con-
nection and after every reset (see page 32). It will
request the following basic adjustments:
• Menu language
• Time
• Date
• Circulation
• Afterheating
• Disinfection
When the last item Save at the end of the commis-
sioning menu is selected, a security enquiry appears.
If the safety enquiry is conrmed, the adjustments
are saved. For further information about the com-
missioning menu see page 13.

b. Activating the main functions
Adjustments for the main functions Circulation,
Afterheating and Disinfection can be made. Main
functions that have not been activated in the com-
missioning menu can now be activated here.
Free relays can be allocated to main functions which
require a relay.The controller always suggests the nu-
merically smallest free relay.
Sensors can be allocated to more than one function.
For further information about the main functions see
page 17.

c. Activating additional functions
Only after the required main functions have been ac-
tivated and adjusted, should the additional functions
be activated.
Any free relay can be allocated to any of the main
functions.The controller always suggests the numeri-
cally smallest free relay.
Sensors can be allocated to more than one function.

tions see page 28.

2.2.3 Adjusting the timer
When the Timer option is activated, a timer is in-
dicated in which time frames for the function can be
adjusted.
First of all, an overview of the current adjustments
is displayed. For each day of the week there is an
overview display. The display can be switched back
and forth between the different days by pressing but-
tons ❷or ❹.
In order to adjust the timer, press button ➄.
First the individual days of the week or all days of the
week can be selected.
The last menu item after the list of days is Continue.
If Continue is selected, the Edit timer menu opens,
in which the time frames can be adjusted.
Adding a time frame:
The time frames can be adjusted in steps of 15 min-
utes.
In order to add an active time frame, proceed as fol-
lows:
ÎMove the cursor to the desired starting point of
the time frame by pressing buttons ❷and ❹.
Con rm the starting point of the time frame by
pressing button ❶.
ÎMove the cursor to the desired ending point of
the time frame by pressing buttons ❷and ❹.
ÎThe end of a time frame can be determined by
pressing button ➄.
ÎIn order to add another time frame, repeat the
last three steps.
Note:
In order to adjust a 24 h time frame, press
button ❶once during the adjustment pro-
cess.
ÎIn order to get back to the overview of current
adjustments, press button ➄again.
