3.3.4 Operating modes and sensor use
The table below shows which sensors are used in which operating
mode.
3.3.5 Heating and cooling
H/C switchover – indoor-outdoor temperature controlled
In this switchover mode, the Climate Controller C-46 switches
between heating and cooling mode depending on the
temperature readings from the indoor and outdoor sensors. The
Climate Controller C-46 can also control an external diverting
valve through a relay contact.
This switchover mode requires that either the Bus master or No
bus function is selected from the H/C switchover menu. See
section 8.7
H/C switchover, page 30. The bus settings refer to
the Uponor Control Systems internal bus.
Both an indoor sensor and an outdoor sensor must be connected
to the Climate Controller C-46 for the switchover function. The
same sensors are also used for the heating and cooling functions
if required.
It is possible to select any of the available heating modes for the
heating function and any of the available cooling functions for
the cooling mode. See sections above.
The Climate Controller C-46 works with the following input for
the H/C switchover function:
• Readings from indoor sensor
• Readings from outdoor sensor
• Setting of Outdoor trigger temp. parameter, see section
8.7.2 Outdoor-indoor/supply temp., page 30
• Setting of Outdoor trigger delay parameter, see section
8.7.2
Outdoor-indoor/supply temp., page 30
• Setting of Indoor trigger temp. parameter, see section
8.7.2 Outdoor-indoor/supply temp., page 30
• Setting of Indoor trigger delay parameter, see section
8.7.2
Outdoor-indoor/supply temp., page 30
H/C switchover – supply temperature controlled
In this switchover mode, the Climate Controller C-46 switches
between heating and cooling mode depending on the primary
supply water temperature.
If the water supplied is below a defined trigger value, the Climate
Controller C-46 switches over to cooling mode. If the water
supplied is above the same trigger value and a defined hysteresis
value, the Climate Controller C-46 switches over to heating mode.
A hysteresis parameter is defined to achieve correct switchover
operations.
This switchover mode requires that either the Bus master or No
bus function is selected from the H/C switchover menu. See
section 8.7
H/C switchover, page 30. The bus settings refer to
the Uponor Control Systems internal bus.
It is possible to select any of the available heating modes for the
heating function and any of the available cooling modes for the
cooling function. See sections above.
The Climate Controller C-46 works with the following input for
the H/C switchover function:
• Readings from supply sensor
• Setting of Supply temperature parameter, see section
8.7.3 Supply water temp., page 31
• Setting of Hysteresis parameter, see section 8.7.3 Supply
water temp., page 31
H/C switchover manual mode
In this switchover mode, the Climate Controller C-46 switches
between heating and cooling when the user manually sets it to
either mode.
The Climate Controller C-46 enters heating mode when the user
selects Heating in the H/C switchover menu. See section 8.7
H/C switchover, page 30.
The Climate Controller C-46 enters cooling mode when the user
selects Cooling in the H/C switchover menu. See section 8.7
H/C switchover, page 30.
