SMART CONTROLLER OPERATION

7.2.1 MAIN HEAT SOURCE
The Smart controller manages the operation of the heat pump by
activating or deactivating it according to demand for DHW or the
space heating circuits.
7.2.2 HEAT CIRCUITS
The Smart controller can manage the operation of one non-
adjustable and up to two adjustable heat circuits. Water
temperature in circuits can set as a fixed flow temperature or
by weather, i.e., water temperature in the circuit is calculated in
accordance with a temperature from the external temperature
sensor. Despite varying outdoor temperature, a room temperature
in heated rooms is kept on a set level.
• Dependent circuits – A thermostat assigned for many circuits.
For example, temperature readings on a installed panel affect
operation of both radiator and underfloor circuits. Commonly
one Thermostat in a central location.
• Independent circuit – Connecting thermostats to measure
room temperature independently and affecting assigned
circuits. It is the way to obtain independency of the circuits,
e.g., in case when one part of the building is used for the
whole year and the second part is used periodically, e.g., for
rent.
If multiple circuits are being controlled you can navigate between
them with a swipe of the screen either to the left or the right.
7.2.3 DOMESTIC HOT WATER
The Smart Controller manages the operation of the Heat Pump
and heating of a DHW cylinder up to a user set temperature. DHW
operation can be programmed in time intervals with a minimum
operation for disinfection mandatory. While the Smart Controller
can also control a DHW secondary circulating pump, their use is
not recommended to minimise wasted energy and running costs.

! NOTE !
The change of the colour under the current value of the
temperature of the circulation and DHW cylinder indicates
whether the temperature is below (blue), above (red) or the
same (green) as the target temperature. Grey indicates the
DHW function is Off.

CIRCUIT SETTINGS

Tapping the screen on the displayed information of the DHW
or a heating circuit you are viewing (if more than 1 heat circuit
installed) will open the circuit settings panel. This will display
various options that can be edited. Refer to Figure 7-4.
