7. Operation and
Maintenance
When the installer has installed your new heat pump, you should check
together that the system is in perfect operating condition. Let the installer
show you where the switches, controls and fuses are so that you know how
the system works and how it should be maintained. Bleed the radiators after
around three days of operation and top up with water if required.
The CTC EcoLogic operates fully automatically. The control system turns on
additional heat when needed, adapts to wood burning when this occurs,
switches to summer mode, etc.
Room Sensor
A room sensor, which should always be itted (up to four room sensors can
be connected), ensures that the temperature in the room is always suitable
and stable. For the sensor to provide the correct signals to the control unit,
radiator thermostats should always be fully open in the area where the room
sensor is located. When adjusting the system, always do so with all radiator
thermostats fully open. The thermostats can be individually adjusted after
a few days in the various rooms. You can select operation without room
sensors by selecting “No” in the menu “Installer/Def. system/Def. heating
circuit/Room sensors”. This can be done if it is dificult to ind a location for
the room sensor, if there are several lats, if the loor heating system has
separate room sensors, or when using an ire place or open stove. The
alarm LED on the room sensor still functions as normal. If you use the ire or
open stove only occasionally, the iring process can affect the room sensor
and reduce the temperature supplied to the radiators. It can then get cold in
the rooms in other parts of the house. The room sensor can temporarily be
deselected during the iring process. CTC EcoLogic thus provides heating to
the radiators using the set heating curve. Refer to the chapter on the “House
heating curve”. The radiator thermostats reduce the heating supplied to the
section of the house where a ire is burning.
"Summer Cellar Heat"
You will often want some background heating in basements/recreation
rooms/bathrooms in the summer months, to avoid raw, damp air. The CTC
EcoLogic takes care of this by setting the minimum permitted primary low
temperature to a suitable temperature (15 to 65°C). See under the menu
“Installer/Settings/heating circuit/Min. primary low °C”. This means that
the temperature supplied to the radiators does not fall below a selected
temperature, for example 35°C. Functional radiator thermostats or shut-off
valves are required in the rest of the house in order for this to work. These
shut off the heating in the rest of the house. The function can also be used
for loor heating in the bathroom to ensure warm loors during the summer.
Night reduction
With night reduction you have the option of automatically varying the
temperature in the house throughout the day, every day of the week. More
information can be found in the chapter “Detail description menus/Night
reduction”.
