The following criteria can lead to abortion of DHW charging by the heat pump:
•
The heat pump cannot complete DHW charging due to a high-pressure fault
•
The heat pump must stop DHW charging because the hot-gas or the flow
temperature approaches its maximum value. The permitted approach to the
maximum value is preset
Line no. Operating line

5024 Switching diff
The DHW request to the heat source is made up of the current DHW setpoint plus the
adjustable setpoint boost.
Heat transfer makes it possible to transport energy from the buffer storage tank to the
DHW storage tank. In that case, the actual buffer storage tank temperature must be
higher than the actual temperature of the DHW storage tank.
The respective temperature differential can be set here.
Storage tank charging can be effected with one or 2 sensors.
It is also possible to implement charging with one sensor and the legionella function
with 2 sensors (setting 3).
User manual RVS61.843
6 The settings in detail
If DHW charging is stopped because the heat
pump has exceeded the number of permitted
charging attempts (2893), the electric immersion
heater (K6) – if present – continues the charging
process.
If no electric immersion heater is used, DHW
charging is resumed as soon as the DHW storage
tank temperature has dropped by the preset DHW
switching differential.
