MAINTENANCE MANUAL

Use the button in the bottom left corner to return to the home screen. Use the arrow button in the bottom right corner to return to previous screen.

For instructions screen, press the ‘i’ button in the top right corner. In case of operation faults, an alarm button is displayed on the top bar.

The following settings are possible for all circuits:

Setting

Description

Example

Reverse control
(ON/OFF)

Reversing of position
valve adjustment
direction

In the OFF position, if voltage
is 0 V, the regulator is in its
extreme right position. In the
ON position, if voltage is 0 V,
the regulator is in its extreme
left position.

Adjustment range
(10...600°C)

The divergence from
target temperature in
which case the position
valve is adjusted from
one extreme position
to another. Factory set

ting: 300 °C.*

If the adjustment range is 140
°C and the target tempera

ture differs from the current
temperature by 14 °C, the
valve is adjusted to 10% of the
maximum. If the tempera

ture changes too quickly, the
adjustment range is increased.
If the temperature changes too
slowly, the adjustment range is
decreased.

Integration time
(5...300 s)

Temperature divergence
correction interval(s).
Factory setting: 50 s.**

If integration time is 10 s, the
valve position is changed once
in every 10 s, if required.

Derivative time
(0...10 s)

Temperature divergence
reaction time. Factory
setting: 0.

The longer the derivative time,
the more the regulator position
changes upon each adjust

ment. Consider that increase
in derivative time may result in
increased regulator fluctuation.

Voltage

(0...10 V)

Position valve control
voltage min and max
values. Factory setting:
0.0-10.0 VAC.

This setting depends on the
regulator used.

Temperature
divergence
(0...10 °C)

Allowed divergence
from target tempera

ture. Factory setting:

°C

At value 5 °C, the regulator
position is changed only after
the difference between the
actual temperature and target
temperature exceeds 5 °C.

Frequency of
measurements
(0...30 s)

How often is the
current temperature
checked. Factory set

ting: 0.

At value 15 s, the current
temperature is checked once
in every 15 s. At value 0 the
checking is continuous.

* Domestic water limit 30 °C
** Domestic water limit 40 s.

5.4.7. Part-power / Full power

The maintenance menu allows switching between full power (default
setting) and part-power, in which case the equipment allows activation
of the electric heating element or some other source of additional heat
simultaneously with the compressor.

5.4.6. Positioning valve control

This screen allows determining the settings of position valves associated
with heat distribution circuits and domestic hot water temperature limit.
Each adjustable circuit has two setting screens.

If the temperature at storage tank bottom part is lower than that of the heat
distribution circuit, the storage tank temperature is automatically increased
so as to meet the heat distribution circuit temperature with additional diver

gence value. Adjustment range 0...10 °C, factory setting 2 °C.
