PrM Pressure visualization mode (rEL to AbS)

rEL = relative pressure; AbS = absolute pressure

All pressure parameters depend on this parameter.

CLP Cooling percentage (Read only)

Displays the percentage of time during which the cooling call was active

in the time interval defined by parameter CLt.

tP1 Temperature probe value (Read only)

Shows the temperature probe value from P1.

PPr Pressure probe value (Read only)

Shows the pressure probe value. The value depends on PrM.

tP2 Temperature from P2 Shows the temperature obtained from conversion of pressure value.

OPP Opening percentage Shows the actual opening percentage of the valve.

d1S Free of voltage digital input

state

(Read only)

Shows the free of voltage digital input.

d2S High voltage digital input state (Read only)

Shows the high voltage digital input state.

Adr RS485 serial address (1 to 247)

Identifies the controller address when connected to a MODBUS compat-

ible monitoring system.

Mod MODBUS (AdU to StD)

AdU = (Only for XWEB systems) In this case, the XEV and the thermo-

static controller are considered standalone controller (it requires a cus-

tom library for XWEB); StD = to use XEV in standalone mode, in this

case normal MODBUS-RTU protocol is used.

Ptb Parameters map (Read only)

It identifies the parameters map written by factory.

rEL Release firmware (Read only)

It shows the firmware release.
