decrease the value of the parameter
concerned. Press to leave this menu and return to the main menu.
RP: Setting the pressure fall to restart
Expresses the fall in pressure with respect to the SP value which causes. Restarting of the pump.
For example if the setpoint pressure is 3,0 bar and RP is 0,3 bar the pump will restart at 2,5 bar.
RP can be set from a minimum of 0.1 to a
maximum of 1 [bar]. In particular conditions (for example in the case of a setpoint lower than the
RP) it may be limited automatically. To assist
the user, on the RP setting page the actual restarting pressure also appears highlighted under the
RP symbol, see Fig. 23.
OD: Type of plant
Possible values "Rigid" and "Elastic" referring to a rigid system and an elastic system. The device leaves the factory with mode "Rigid"
suitable for the majority of systems. In the presence of swings in pressure that cannot be stabilised by adjusting the parameters GI and
GP, change to mode "Elastic".
IMPORTANT:
The regulating parameters GP and GI also change in the two configurations. In addition the GP and GI values set in mode
"Rigid" are stored in a different memory from the GP and GI values set in mode "Elastic". So, for example, when passing to
mode "Elastic", the GB value of mode "Rigid" is replaced by the GB value of mode "Elastic" but it is kept and will reappear
again when returning to mode "Rigid". The same value shown on the display has a different weight in one mode or in the other
because the control algorithm is different.
MS: Measuring system
Set the measuring system, choosing between metric and Anglo-American units. The quantities displayed are shown in Table 11.
The flow in Anglo-American units (gal/min) is indicated adopting a conversion factor of 1 gal = 4.0 litres, corresponding to the
metric gallon

AS: Association of devices
Enables connection/disconnection mode with at the most 5 compatible elements:
esy → Other Esybox pump for operation in a pump set composed of max 4 elements.
•
DEV → Any other compatible devices
•
The icons of the various connected devices are displayed on page AS with below an identifying
acronym and the respective reception power. An icon lit with a fixed light means that the device is
connected and working correctly; a stroked through icon means the device is configured as part of
the network but is not found.
