CAUTION
The following procedures require access to the hydro unit electrical box while the system electrical
supply is switched ON
Please ensure all National and Local regulations are followed with regards to working on LIVE
equipment
Function Code Reset Procedure:
The following procedure explains how to reset the hydro unit function codes back to the factory default
settings:
1. Turn the ESTIA system OFF using the ESTIA remote controller
2. Turn OFF the power supply to the ESTIA system
3. Remove the hydro unit front cover and the cover to the hydro unit electrical box
4. Set DPSW06_1 and DPSW06_2, on the hydro unit PCB, to ON
5. Turn ON the power supply to the ESTIA system
– the yellow LED, near the MCU, will start to flash
(SLOW)
6. Press and hold the tactile switch, SW07, for 15 seconds. During this time the yellow LED will go
through a sequence of flashing / LED OFF / LED ON
7. Turn OFF the power supply to the ESTIA system
8. Set DPSW06_01 and DPSW06_2, on the hydro unit PCB, to OFF
9. Replace the cover to the hydro unit electrical box and the front cover for the hydro unit
10. Turn ON the power supply to the ESTIA system
11. Reset function code FC01 to the correct capacity code. L09 fault code will be displayed if FC01 is
not set to show the correct capacity setting for the system
Component Operation Check Mode using Hydro Unit PCB:
This mode allows the commissioning engineer to check the operation of various components (pump, 2 way
valve, 3 way valve etc.) installed in the heating circuit.
1. Turn the ESTIA system OFF using the ESTIA remote controller
2. Turn OFF the power supply to the ESTIA system
3. Remove the hydro unit front cover and the cover to the hydro unit electrical box
4. Set DPSW06_2 to ON
5. Turn ON the electrical supply to the ESTIA system
