DeltaControl – Operation
EN
General
The DeltaControl is a temperature differ-
ence controller with automatic plausibil-
ity check. It controls solar systems that
use Solvis collectors and the Solvis-
Therm drinking water tank.
Alternatively, the DeltaControl can also
be used as a load pump controller, for
example, with fireplaces with back
boiler pockets or with solid fuel boilers.
Function
The DeltaControl compares the temper-
ature of the collector (T1) with that of
the SolvisTherm hot water storage tank
(T2).
The control switches the solar pump on
when a configurable temperature differ-
ence (dT max) between the collector
and the storage tank is exceeded.

In this case, the boiler or flow sensor is
connected to T1 and the boiler pump to
A1. The controller is intended to be
used in dry rooms in private households
or business premises.
Operating this unit for any other pur-
pose is prohibited. Exceptions require
express written approval or statement
from Solvis in advance.
If the temperature difference falls below
the defined minimum value (dT min), T1
falls below the defined minimum value
(T min), or the storage tank sensor
reaches the defined maximum value
(T max), the solar pump is switched off.
The storage tank maximum value pro-
tects against calcification, damage to
the storage tank coating, and scalding.
