Adjustment, charge flow
For correct function of the heat pump over the entire
year, the charge flow must be correctly adjusted.
If an Kaukora indoor module Jäspi Tehowatti AIR or ac-
cessory controlled charge pump is used for the control
module Jäspi MCU 40, the control tries to maintain an
optimal flow across the heat pump.
Adjustment may be required, especially for charging a
separate water heater. It is therefore recommended to
have the option of adjusting the flow across the water
heater using a trim valve.
1. Recommendation if there is insufficient hot water
and information message "high condenser out"
during hot water charging: increase the flow
2. Recommendation if there is insufficient hot water
and information message "high condenser in" during
hot water charging: reduce the flow
