EKRTCTRL1

2.6  EKRTCTRL1 connections

H2*

water temperature probe (10 kΩ)

AIR

air temperature probe (10 kΩ)

M1

DC inverter fan motor

S1

grill safety micro-switch

Y1

water solenoid valve (230V/ 50Hz 1A output 
voltage)

Y2

mobile flap connection
230V/ 50Hz 1A output voltage.

L-N

230V/50Hz electrical power supply

BO

boiler consent output (free contact max 1A)

CH

chiller consent output (free contact max 1A)

CP

presence input sensor (if closed, the fan coil unit

If after switching the power on the board 
detects the H2 probe, start-up occurs in normal 
conditions with the minimum water temperature 
when heating (30°C) and maximum when 
cooling (20°C). 
The board also has a function when there is no 
probe, in such cases the fan stop minimum and 
maximum thresholds are ignored.
