1 Overview
The HKM3 heating circuit extension module enables
the control of an additional heating circuit. A simple
VBus®connection is enough to add a complete weather-
compensated heating circuit to the controller.
The HKM3 is equipped with 6 sensor inputs, one of
which can be used for the optional RTA11-M remote
control. Four semiconductor relays are available for
controlling the mixing valve and the heating circuit
pump.Additionally, a potential-free relay takes care of
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.

2.2 Electrical connection
The device is supplied with power via a mains cable.
The power supply must be 100 ... 240 V~ (50...60 Hz).
The device is equipped with five relays to which loads
can be connected with correct polarity (Rx/N):
17 ...21 = Ground conductor terminal
15 ... 16 = Potential-free relay
N, 23 = Relay 4
N, 25 = Relay 3
N, 27 = Relay 2
N, 29 = Relay 1
N = Neutral conductor
Connect the temperature sensors (S1 to S6) to
the corresponding terminals with either polarity:
1/2 = Sensor 1
3/4 = Sensor 2
5/6 = Sensor 3
7/8 = Sensor 4
9/10 = Sensor 5
11/12 = Sensor 6
The RTA11-M remote control can optionally be
connected to the terminals 9/10.
Connect the controller to the HKM3 via the RESOL
VBus®. Connect the RESOL VBus®to the terminals
marked “VBus” with either polarity:
13 = VBus®terminal
14 = VBus® terminal
Connect the mains cable to the following terminals:
30 = Neutral conductor N
31 = Conductor L
17 = Ground conductor terminal
Attach flexible cables to the housing with the en-
closed strain relief and the corresponding screws.
Note
Connecting the device to the power supply
must always be the last step of the instal-
lation!
2.3 Sensor and relay allocation of the HKM3
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!
WARNING! Electric shock!
Upon opening the housing, live
parts are exposed!
ÎAlways disconnect the
controller from power
supply before opening the
housing!

2.4 Application example 3 Commissioning, operation and
adjustment
ÎEstablish the power supply
The HKM3 runs an initialisation phase during which
the operating control lamp flashes. Afterwards, the
module begins normal operation and indicates the
measured values of the sensors connected.
If the power supply is established but the module is
not yet connected to and registered in the controller,
the HKM3 works like a display unit without control
function.
ÎConnect the HKM3 to the controller via the
VBus®.
ÎRegister the HC module in the options menu of
the controller.
All adjustment and display values are listed in the cor-
responding (HC-Module) menu of the controller.
If more than 1 HKM3 is connected to one controller,
each HKM3 must be assigned with a sub-address. To
do so, proceed as follows in the HKM3 menu:
Select the menu channel SA by pressing buttons 1 and 2.
ÎPress button Set, the symbol flashes
ÎAssign a sub-address to the HKM3 (e. g. 2for the
second, 3for the third HKM3 connected)
Note:
The HKM3 must be registered in the con-
troller connected!
ÎAll adjustments for the HKM3 must be
made in the corresponding menu of the
controller connected!
ÎConsult the controller manual in order
to use all functions of the HKM3!
3.1 Flashing codes of the control lamp
Green: Everything OK
Red/green flashing: Initialisation, manual mode
Red flashing: Error
The relays of the HKM3 can be manually switched on
(I), switched off (0) or put into automatic mode by
means of the slide switch. When the slide switch is
set to I, the states of the relays can be determined in
the channel MM.
• Manually OFF = 0 (left)
• Manually ON = I (right)
• Automatic mode = Auto (centre)
In the parameter MM, different relay states can be
adjusted:
0 = R1 on
1 = R1 on, R2 on
2 = R1 on, R5 on
3 = R1 on, R2 on, R5 on
M1 ... M5
By means of the parameters M1 ...M5, the states of the
individual relays can be adjusted in automatic mode
(slide switch set to Auto). The adjustments made in
M1 ... M5 are overridden by the parameter MM when
the slide switch is set to I.
3.2 Manual mode
Adjustment range: 0,Auto, I
Factory setting: Auto
Note
After service and maintenance work, set the
relay mode back to Auto. Normal operation
is not possible in manual mode.

and registered in the controller. The HKM3 then
works like a display unit without control function.
The following adjustments are available:
0 = Resistance (the resistance measured is displayed
regardless of the sensor type)
1 = Pt1000
2 = KTY
3 = Pt500
4 = RTA11-M (remote control)
As soon as a connection between the HKM3 and a
controller has been established,the adjustments made
for the sensor types in T1 ...T6 are overwritten. Each
HKM3 connected then has the sub-address 1 and the
sensor input adjustments listed in the following table.
Afterwards, a sub-addresses has to be assigned to
each individual HKM3 (again, if done before).
Sensor Sensor type
T1 1 (Pt1000)
T2 1 (Pt1000)
T3 1 (Pt1000)
T4 1 (Pt1000)
T5 4 (RTA11-M)
T6 1 (Pt1000)
The HKM3 display indicates the measured values of
the sensor input to which a sensor is connected.The
values are indicated regardless of whether the con-
troller connected requires them for heating circuit
control.
Note
If the mains connection is established but the
module is not yet connected to and regis-
tered in the controller, the following addi-
tional adjustment channel appears:

Problems and solutions
Problem description Possible causes and solutions
The heating is permanently active
• Check if the remote control is set to rapid warm-up
• The outdoor temperature sensor is not correctly
positioned or defective (see Sensor fault)
• The temperature value for the summer operation
is too high
The heating is permanently off
• Check if the remote control is set to heating
circuit off
• The pump setting in the HKM3 is set to 0(off)
• The flow sensor is defective (see Sensor fault)
• The temperature value for the summer operation
is too low
The heating heats up very slowly • Check and, if necessary, increase the runtime of the
mixing valve
Despite the heating breaks of the radiators,
it is permanently too warm
• Check the heating curve adjustment and,
if necessary, decrease it
• The maximum flow temperature value is too high.
If necessary, decrease it
• Check the setting of the remote control and,
if necessary, choose a lower setting
• The adjusted day correction value is too high.
If necessary, decrease it
Even though the heating is active, it ispermanently too
cold
• Check the heating curve adjustment and,
if necessary, increase it
• The maximum flow temperature value is too low.
If necessary, increase it
• Check the setting of the remote control
• Check the adjusted time
• Check the adjusted time frames for the night
correction and, if necessary, change the setting
such that unwanted temperature decreases cannot
occur
6 Accessories
Sensors
The product range includes high-precision platinum
temperature sensors,flatscrew sensors, outdoor tem-
perature sensors, indoor temperature sensors, cylin-
drical clip-on sensors, also as complete sensors with
immersion sleeve.
Overvoltage protection device
In order to avoid overvoltage damage at collector
sensors (e.g. caused by local lightning storms), we
recommend installting the overvoltage protection
RESOL SP10.
RESOL SP10 Article no.: 180 110 70
RTA11-M remote control
The remote control RTA11-M is designed for con-
nection 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 con-
trol additionally allows the functions “heating circuit
off” and “maximise flow temperature”.
