Heating cycle
Modulating temperature regulation with compensated set
point - LOW temperature
The function is enabled by setting dip switch 1 to the OFF
position.
When the function is enabled, the flow temperature is modified
according to the temperature detected by the compensation
probe.
This keeps the actual thermal output of the under floor heating
and therefore the ambient thermal load under control. The
thermal response time of the system is thus minimised.
Safety and alarms
Error codes associated with faults signalled by the lighting up of
the FAULT LED are also shown on the display (see page 7).
Operating Cycles
Maintenance
All maintenance procedures should be carried out by an
qualified technician.
Regular maintenance guarantees better efficiency and helps to
save energy.
Before carrying out any maintenance, repair or part
replacement work, proceed as follows:
•
Switch off the electric supply
•
Remove the cover
•
Close the shut-off valves
•
Empty the HIU using the drain cocks provided.
Heat exchanger replacement
•
To remove the heat exchanger, loosening the 2 hexagon
headed screws holding it in place (A)
•
Replace the heat exchanger and the O-rings.
•
Refit and tighten the two fixing screws (A) with a maximum
torque of 3.5 N/m.
N.B. The pins fixing the heat exchanger are positioned in such a
way as to allow it to be placed only in the correct direction.
Maintenance
Cleaning the strainer element
The HIU has a strainer on the flow (inlet) from the centralised
boiler plant and on return from the heating circuit.
To clean these strainers, carry out the following maintenance
procedure:
•
Unscrew the cap (B)
•
Remove the strainer mesh and discard any impurities
•
Put the strainer mesh back in
•
Screw the cap back on.
