3.3.3 Room thermostat control – Using the leaving water temperature home pages
INFORMATION
The leaving water is the water that is sent to the heat emitters. The desired
leaving water temperature is set by your installer in accordance with the heat
emitter type. Example: Underfloor heating is designed for lower leaving water
temperature than radiators and heat pump convectors and/or fan coil units. You
only have to adjust leaving water temperature settings in case of problems.
For more information about the leaving water temperature, see the user
reference guide.

In case of frequent domestic hot water operation, frequent and long space
heating interruption will happen.
Scheduled mode
In scheduled mode ( ), the DHW tank produces hot water corresponding to a schedule. The best time to allow the tank to produce hot water is at night, because the space heating demand is lower.

In scheduled + reheat mode ( ), the domestic hot water control is the same as in scheduled mode. However, when the DHW tank temperature drops below a preset value (=reheat tank temperature hysteresis value; example: 35°C), the DHW tank heats up until it reaches the reheat set point (example: 45°C). This ensures that a minimum amount of hot water is available at all times.

4 Setting the energy prices
If your system’s savings mode is set to Economical, it allows you to set:
a fixed gas price
3 electricity price levels
a weekly schedule timer for electricity prices.
The savings mode is set by the installer and can be either ecological or economical. In ecological mode, the primary energy use is minimised; in economical mode, the running costs. Discuss with the installer which savings mode is preferred. Refer to the installation manual for more information.
Example: How to set the energy prices on the user interface?
Price Gas: 5.3 euro cent/kWh
Value in breadcrumb [7.4.6]=5.3
Gas: 4.8 pence/kWh Electricity: 12 euro cent/kWh

6 Energy saving tips
Tips about room temperature
Make sure the desired room temperature is NEVER too high, but ALWAYS according
to your actual needs. Each saved degree can save up to 6% of heating costs.
Do NOT increase the desired room temperature to speed up space heating. The
space will NOT heat up faster.
When your system layout contains slow heat emitters (example: underfloor
heating), avoid large fluctuation of the desired room temperature and do NOT
let the room temperature drop too low. It will take more time and energy to
heat up the room again.
Use a weekly schedule for your normal space heating needs. If necessary, you
can easily deviate from the schedule:
For shorter periods: You can overrule the scheduled room temperature. Example:
When you have a party, or when you are leaving for a couple of hours.
For longer periods: You can use the holiday mode. Example: When you stay at
home during your holiday, or when you go away during your holiday.
Tips about DHW tank temperature
Use a weekly schedule for your normal domestic hot water needs (only in
scheduled mode).
Program to heat up the DHW tank to a preset value (Storage comfort = higher
DHW tank temperature) during the night, because then space heating demand is
lower.
If heating up the DHW tank once at night is not sufficient, program to
additionally heat up the DHW tank to a preset value (Storage eco = lower DHW
tank temperature) during the day.

Make sure the desired DHW tank temperature is NOT too high. Example: After
installation, lower the DHW tank temperature daily by 1°C and check if you
still have enough hot water.
Program to turn ON the domestic hot water pump only during periods of the day
when instant hot water is necessary. Example: In the morning and evening.
7 Maintenance and service
7.1 Overview: Maintenance and service
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
As end user, you have to:
Keep the area around the unit clean.
Keep the user interface clean with a soft damp cloth. Do NOT use any
detergents.
Regularly check if the water pressure indicated on the gas boiler is above 1
bar. Switch off the boiler to see the pressure on the main display of the gas
boiler. Ignore the error that appears on the user interface. When you turn the
gas boiler back on, the error will disappear.
Make sure that electricity and gas prices defined in the user interface are
up-to-date.
Refrigerant This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
NOTICE Applicable legislation on fluorinated greenhouse gases requires that
the refrigerant charge of the unit is indicated both in weight and CO2
equivalent. Formula to calculate the quantity in CO2 equivalent tonnes: GWP
value of the refrigerant × total refrigerant charge [in kg] / 1000
Please contact your installer for more information.
WARNING: FLAMMABLE MATERIAL The refrigerant inside this unit is mildly
flammable.
WARNING The appliance shall be stored in a room without continuously operating
ignition sources (example: open flames, an operating gas appliance or an
operating electric heater).
WARNING Do NOT pierce or burn refrigerant cycle parts.
Do NOT use cleaning materials or means to accelerate the defrosting process
other than those recommended by the manufacturer.
Be aware that the refrigerant inside the system is odourless.
7 Maintenance and service
WARNING
The refrigerant inside the unit is mildly flammable, but normally does NOT
leak. If the refrigerant leaks in the room and comes in contact with fire from
a burner, a heater, or a cooker, this may result in fire, or the formation of
a harmful gas.
Turn off any combustible heating devices, ventilate the room, and contact the
dealer where you purchased the unit.
Do NOT use the unit until a service person confirms that the part from which
the refrigerant leaked has been repaired.

For the symptoms listed below, you can try to solve the problem yourself. For
any other problem, contact your installer. You can find the contact/helpdesk

If the problem recurs daily, do one of the following:
Increase (decrease) the room temperature preset value. See the user reference guide.
Adjust the room temperature schedule. See “3.6 Schedules: Example” 4[ 6].
The desired room temperature cannot be reached.
Increase the desired leaving water temperature in accordance with the heat emitter type. See “Room thermostat control – Using the leaving water temperature home pages” 4[ 5].

the gas boiler is not allowed to work because of an installer setting.
When the outdoor temperature is higher than the equilibrium temperature [501], the gas
boiler is not allowed to work.
Do not set the equilibrium temperature [501] too high, because this would result in much less heat pump operation.

8.3 Symptom: Heat pump failure
When the heat pump fails to operate, the gas boiler can serve as an emergency
back-up heater and either automatically or nonautomatically take over the
entire heat load.
When auto emergency is activated and a heat pump failure occurs, the boiler
will automatically take over the heat load.
When auto emergency is not activated and a heat pump failure occurs, the
domestic hot water and space heating operations will stop and need to be
recovered manually. The user interface will then ask you to confirm whether
the boiler can take over the entire heat load or not.

INFORMATION
When the gas boiler takes over the entire heat load, gas consumption will be
considerably higher.

(a) We recommend to purge air with the air purge function of the unit (to be performed by the installer). If you purge air from the heat emitters or collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you purge air from heat
emitters or collectors, check if an error or is displayed on the home pages of
the user interface.
If not, you can purge air immediately.
If yes, make sure that the room where you want to purge air is sufficiently
ventilated. Reason: Refrigerant might leak into the water circuit, and
subsequently into the room when you purge air from the heat emitters or
collectors.
9 Disposal
NOTICE
Do NOT try to dismantle the system yourself: dismantling of the system,
treatment of the refrigerant, oil and other parts MUST comply with applicable
legislation. Units MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
