CLIMATE CONTROLLER C-46 - INSTALLATION AND OPERATION MANUAL
6
3 Climate Controller C-46 overview
This section is a brief description of the Climate Controller C-46
as a system component and its operating modes.
3.1 Description
The Climate Controller C-46 is a primary controller for heating,
cooling and meltaway systems.
Examples of applications are:
• Underfloor heating and cooling systems
• Wall heating and cooling systems
• Ceiling cooling and heating systems
• Radiator heating system
• Meltaway system
Its main function is to regulate supply water temperature by
controlling a mixing valve actuator.
Other functions include:
• Circulation pump control
• Output for heating/cooling switchover relay
• Dew point control
3.1.1 Heating and cooling system example
The figure below shows how the Climate Controller C-46 can be
set up in a climate system. The figure also shows several system
components that can be connected to the Climate Controller
C-46. The system can use either wired sensors or radio
thermostats.
The figure is applicable for heating, cooling and heating/cooling
switchover systems. Some of the components are intended for
use with specific system modes as indicated in the table below.
NOTE!
Only Uponor sensors and thermostats should be used
in combination with the Climate Controller C-46.
