Auxiliary preheater - max power
Flow-through heater has maximum capacity of 9 kW
(3 phases). The capacity of the fl ow-through heater
is divided into 3 gears. Possible operating capacities
are as follows: 3, 6, and 9 kW. Maximum capacity of
the fl ow-through heater is set in menu 5.1.12.

functions are active.
• Domestic hot water is not heated.
• Constant temperature in the supply pipeline;
more information to be found in the Chapter
Emergency Mode Thermostat.
IMPORTANT
During emergency operation, DHW heating is not pos-
sible.
Emergency Mode Thermostat
In the emergency mode, the supply temperature is set
using a thermostat (BT30). It must be set according to
the demand of the circuits in operation. The available
regulation range is between 6 and 67°C. Remember
that for floor heating, the settings must be min. 20°C,
max. 35-45°C in order to preserve heat comfort in the
room and assure effective system operation.
IMPORTANT
The maximum available heater power in emergency
mode is 3kW.
IMPORTANT
The temperature on the thermostat must be set ac-
cording to the installation requirements. Too high a
temperature can damage the insulation.

Preparations

1. Check whether the switch in the controller is in
the position „ ".
2. Check whether the drain valve has been com-
pletely closed, and whether the temperature lim-
iter has not been activated (FD1).
3. Compatible Alpha innotec air/water heat pumps
have been listed in the Connection Options sec-
tion.

Filling and venting

Filling the DHW heater
at HT 6Split / HT 12Split
1. Open the hot water tap in the building to the tank.
2. Open the valve cutting off cold water. When doing
so, the valve should be completely open.
3. When water starts to fl ow out of the hot water tap,
DHW heater is full and the tap can be closed.
Filling and venting the heating system
and HT 6Split / HT 12Split
1. Open the vent at the top point of the heating sys-
tem.
2. Set all the isolation valves in the position allowing
for fl ow in all circuits.
3. Open the valve for fi lling the heating installation
and fi ll it with the heating medium.
4. Close the vent when the heating medium fl ows
out of it continuously (without air bubbles).
5. Control the manometer showing pressure in-
crease. Fill the system until the pressure of 2 bar,
and then close the fi lling valve.
6. Start the circulation pump of the heating system
every now and then, while opening the vents
placed on the heating circuit.
7. Open the safety valve until the pressure at the
manometer falls down to about 1 bar of the nor-
mal operating range.
8. If, while venting, the pressure drops down below
1 bar, supplement the heating medium in the cir-
cuit.
