“Solar” function
34
The "Storage tank priority" function controls the tank charging of dual tank systems. There
are the following types of dual tank systems:
•
Systems with two separate storage tanks
•
Systems with a stratified storage tank (a storage tank with two heat exchangers, one on
top of the other)
•
Systems with a storage tank in combination with a swimming pool
•
etc.
In control mode, the first storage tank is charged as a storage tank with priority 1. If more
heat is generated than required, the excess energy is fed into the second storage tank
(storage tank with priority 2). In the case of the stratified storage tank, the top heat
exchanger is defined as the first storage tank.
For this function you can set the following parameters:
•
Basic settings/Solar circuit/Hydraulic layout
•
Basic settings/Solar circuit/Charging break
•
Basic settings/Solar circuit/Priority
•
Program/Solar circuit/Storage tank active

Setting the "Parallel charging" function
This function is available only for 2 or more storage tank systems with pumps or
pump two-way valves. 2 storage tanks are charged in parallel.
This function allows you to charge 2 storage tanks simultaneously. This requires the
charging conditions for one storage tank to be fulfilled. At the same time the parallel
charging conditions for one storage tank with lower priority must be fulfilled. Both pumps
run with a pump output of 100 %. For layouts with valves, both valves will be opened. The
energy output is divided between the two storage tanks.
For this function you can set the following parameters:
•
Basic settings/Solar circuit/Hydraulic layout
•
Basic settings/Solar circuit/Parallel charging
•
