CLIMATE CONTROLLER C-46 - INSTALLATION AND OPERATION MANUAL
8
Setpoint adjustment and definitions are the same as for the
case with radio thermostats connected to the Climate
Controller C-46, see above.
3.2.5 Sensor priorities
When sensors and thermostats are connected to the Climate
Controller C-46 in different ways, the following priorities apply:
1. Thermostats linked to the Climate Controller C-46 through an
antenna have the first priority.
2. Sensors directly connected to the Climate Controller C-46
have the second priority.
3. Thermostats linked to the Controller C-56 Radio, connected
to the Climate Controller C-46, have the third priority.
Example
A house is heated using a system set up in Heating – indoor
controlled mode. In this case, a Thermostat T-75 Radio is linked
to the Climate Controller C-46, using the antenna. As a backup,
an indoor sensor is directly connected to the Climate Controller
C-46.
Under normal conditions, the Climate Controller C-46 will use the
readings from Thermostat T-75 Radio to monitor the indoor
temperature.
However, if the batteries in the Thermostat T-75 Radio fail, it will
not be able to send any temperature readings to the Climate
Controller C-46. Then the Climate Controller C-46, will switch the
monitoring to the inhouse sensor instead.
When the used batteries in the Thermostat T-75 Radio are
replaced, the Thermostat T-75 Radio will go back to sending
temperature readings again. Then the Climate Controller C-46
senses this and the monitoring of indoor temperature is switched
back to the Thermostat T-75 Radio.
3.3 Operating modes
The following operating modes are available for the Climate
Controller C-46:
• Heating
• Cooling
• Heating and cooling
• Meltaway
The following sections give a brief description of the different
operating modes and list which sensors must be connected and
which operating parameters must be set as a minimum.
3.3.1 Heating modes
Depending on the sensors used, the following heating modes are
described in the sub-sections below:
• Heating – fixed supply
• Heating – outdoor controlled supply
• Heating – outdoor controlled supply with indoor
compensation
• Heating – indoor controlled
• Heating – outdoor controlled average
See also an overview in section 3.3.4 Operating modes and sensor
use, page 10.
Heating – fixed supply
In this operating mode, the Climate Controller C-46 maintains a
constant supply temperature.
The user must adjust the Heating supply setpoint parameter to
meet the heating need of the house.
The Climate Controller C-46 uses the following input:
• Readings from supply sensor
• Setting of Heating supply setpoint parameter, see section
7.3.3 Heating supply setpoint, page 20
Heating – outdoor controlled supply
In this operating mode, the Climate Controller C-46 adjusts the
supply temperature depending on the outdoor temperature. That
is to say, the supply temperature increases with falling outdoor
temperature and the other way around.
When the parameters are correctly set, the indoor temperature is
kept at a constant level. See also section 10.2
Adjusting the heat
curve, page 46.
The Climate Controller C-46 works with the following input:
• Readings from supply sensor
• Readings from outdoor sensor
• Readings from floor sensor (optional)
• Setting of T-slope parameter, see section 7.3.5 T-slope,
page 20
• Setting of T-adjustment parameter, see section 7.3.6 T-
adjustment, page 20
• Setting of Min./Max. supply parameter, see section 6.2.4
Heating, page 16
Heating – outdoor controlled supply with indoor
compensation
In this operating mode, the Climate Controller C-46 adjusts the
supply temperature depending on both the outdoor and indoor
temperatures. That is to say, the supply temperature increases
with falling outdoor temperature and the other way around.
When the parameters are correctly set, the indoor temperature
will be kept at a constant level. See also section 10.2
Adjusting
the heat curve, page 46.
The supply temperature is adjusted as the Climate Controller
C-46 compares the readings from the indoor sensor against the
indoor setpoint temperature. A deviation of 1 °C in indoor
temperature results in a 4 °C compensation of the supply
temperature (default setting).
The Climate Controller C-46 works with the following input:
• Readings from supply sensor
• Readings from outdoor sensor
• Readings from indoor sensor
• Setting of Indoor setpoint parameter, see section 7.3.4
Indoor setpoint, page 20
• Setting of T-slope parameter, see section 7.3.5 T-slope,
page 20
• Setting of T-adjustment parameter, see section 7.3.6 T-
adjustment, page 20
