*1 by 1-wire bus up to 20 sensors. Additional temperature sensors by CAN network
*2 Two separate CAN networks, 1x private (appartment), 1x heating system (building)
*3 up to 8 °CALEON can be supplied with 24VDC by °CALEONbox. When connecting more °CALEONs, an additional power supply is required. Alternatively, an external 230VAC thermostat can be operated for each zone.
*4 for measuring tap temperature and flow for domestic hot water control
*5 via 230VAC relays on/off, or speed-controlled via PWM
*6 Flow temperature control is done according to room temperature, optionally weather-compensated or combination of weather-compensation with room temperature influence
*7up to 8 heating zones with up to 3x 230VAC actuators as NO or NC design also with PID control
*8 potential-free relay contact, 0-10V or PWM signal or via CAN network
*10 adjustable via °CALEON or °CALEON Clima
*11 via SOREL Data Logger (soon also via °CALEON 24VDC Smart Thermostat with Wifi)
*12 separately in every zone where °CALEON Clima is installed
