Indoor Temperature With Double Heat Curves; Restriction Of Electrical Elements - ComfortZone RX35 User And Installation Manual

ComfortZone RX35/RX50/RX65
Thermostats for room temperature control should only be used in
bedrooms.
Note! The function of the heat pump can be seriously disturbed if the
indoor temperature is regulated by room thermostats in all rooms.
2.7.1 Problems that may arise.
Problems can arise with control method IN if the internal exhaust air
sensor is disturbed by hot air coming through your ventilation system
from heat sources such as a dryer, fireplace or sauna.
The heat pump becomes "tricked" and believes that the house is warmer
than it really is.
If this is a problem, we recommend an external indoor sensor that is
placed in a suitable place where it does not detect the hot air from the
external heat sources, see section 2.11 below.

2.8 Indoor Temperature with double heat curves.

There is a possibility of two different heating zones being controlled via the heat
pump. A function that is useful when heating the house with radiators and underfloor
heating.
If double heat curves are used there is settings for CW Heating curve 2, CW Room
setting 2 and CW Room factor 2 in the /Heating settings/ menu.
Zone 1 and zone 2 are adjustable individually.
Fine tuning of the temperature is common for zone 1 and zone 2.
For installation of double heat curves, see section 11.10.

2.9 Restriction of electrical elements.

The control board's automatic control of the indoor temperature can sometimes cause
the electrical elements to be switched on even though the indoor temperature
exceeds the set value. Allowing this provides the best temperature control, but can
also cause some increase in power consumption.
To avoid this, the parameter "CW Heater allowed" is set to 0.0° C as the factory
setting (default value).
The electrical elements are blocked if the indoor temperature exceeds the set value +
0.0° C, i.e. set value.
If " CW Heater allowed" is set " at -1.0° C, electrical elements are blocked if the indoor
temperature exceeds set value -1.0° C.
The display shows also the absolute value, i.e. (Set indoor temp – CW Heater
allowed.). In menu (If CW Room setting is 21°C):
"CW Heater allowed (20,0) -1.0°C "
If " CW Heater allowed " = IN is selected, the value is recommended to be -0.5° C.
Parameter " CW Heater allowed" can be found under "Advanced settings" /
"Heating settings" / " CW Heater allowed ".
