compressor will start up. Make sure that there are no strange
noises coming from it. If the compressor sounds abnormal,
stop the unit immediately and check the compressor. If the
compressor runs well please check the pressure of the
refrigerant.

Following the above, check whether the power input and
running current being drawn by the unit is in line with this
manual. If not please stop the unit and check for any
problems.

If the unit is supplying a heating manifold, adjust the
actuators on the manifold(s) to balance the heating being
received in all areas of the system.

Check that the outlet water temperature is stable and
increasing smoothly towards the target temperature. The
return water temperature should move in line with the flow
temperature with around a 4 deg C. difference between the
flow and return water temperatures.
 The parameters of the unit controller are factory set and you
must not change them without consulting your installer or
ESP. The exceptions to this are the running temperature (or
flow temperature) of the system and the time. Section 10
explains how to view the various parameters although the
default view will show the current status of the system (see
10.1).
