By including the Icon2 in the system, the user will be able to control the Icon2 system via the same App that controls the rest of the house. Icon2 is connected to Zigbee-based smart home solutions by opening up the App of the Zigbee smart home solution of your choice and adding the Icon2 system as a new device. Depending on the smart home solution, this can either be done by simply pressing the OK button once or, in the case of a Zigbee 3.0 solution, first scanning the QR code in the lower left corner on the MC front and then clicking the

The pump and heat demand signal will activate whenever there is a heating demand for at least one circuit. Both the pump (PWR1) and the heat demand signal (RELAY) are set to have a switch-on delay of 3 minutes by default. In PWM+ mode, the Danfoss Icon2™ makes use of automatic balancing. During periods with a greater need for heat, this decreases the time spent ‘on’ for shorter pipes in small rooms and prioritizes longer pipes in large rooms within the system. The process is automatic and continuous. It ensures more efficient

Disabling cooling (Bathroom) If there is a bathroom with underfloor heating and an Icon2™ room thermostat, you may want to disable cooling for this room. Cooling a bathroom will cause condensation to form on the floor. There are two ways to disable cooling mode for a room: 1. Using the Installer App on a smartphone 2. Using the installer menu on the thermostat itself To do so, set the ME.7 setting to OFF A relay or potential-free contact is connected to input IN2 to control the changeover between heating and cooling modes. When the external contact is closed, the system will change over to cooling mode. AB432956914381en-010201 © Danfoss | HydronicS | Sub-syste
