• Room humidity reading and adjustment
• Water temperature reading (water sensor as an optional)
• Manual/automatic regulation of the fan speed with ON -OFF step and modulating control
• Automatic adjustment of valve opening with ON/OFF and modulating controller
• Manual and automatic switching of heating and cooling mode depending on the water temperature within the heat exchanger or on the room temperature,
with a selectable neutral zone
• Clock and hourly timer-programmed operation
• 3 Analogue outputs for controlling modulating evices -10V
• E conomy function and minimum temperature
• 1 Digital outputs for controlling (On/Off) external devices (novoltage contacts)
• Serial port for RS485 connection
• Serial port for OC connection
• 3 digital inputs for remote setting of ON OFF, Economy, operating modes
Operating mode
The controller is equipped with a programmable display to show and set all the functions of the hydronic unit through a dedicated interface with the parameter
description.
DISPKB - EVO DISP on-board installation kit
it consists of the bracket (same color of the cabinet) and the appropriate mounting screws.
EVOBOARD - EVO BOARD on-board installation kit
it includes a power board, a connection terminal board and appropirate mounting screws.
TED10 - on-board or wall-mounted electronic controller for BLDC fan control and one or two valves ON/OFF 230V.
Main functions:
• It supports terminal units equipped with BLDC electric motor thanks to its internal 0-10 V signal generator
• for 2 and 4 pipes systems
• Manual and automatic fan speed adjustment mode
• temperature-based management of water flow enabling
TEDKB - TED on-board installation kit
it consists of the bracket (same color of the cabinet) and the appropriate mounting screws.
TED SWA - Water or air temperature sensor for controls TED
NTC resistive probe connected directly to the microprocessor control TED10, depending on connetion, it measures indifferently the temperature of the water
passing through the finned coil or the temperature of the air inlet to the fan coil.
Ventilation is disabled in heating and cooling operation mode if the detected temperature is less than 30 ° C and above 22 ° C respectively.
