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

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”.
