MANAGEMENT SYSTEM 

PARAMETERS MENU 

 

The  submenu  "PARAMETERS  MENU"  allows  you  to 

remotely manage the boiler.

 

Pushing the 

 and 

 buttons, you scroll through the various 

items. 

 

First page: 

 

 

Second page: 

 

 

The first item  "Read" allows you to read the parameters of 

the system remotely. 

Pushing the OK button is activated the first page of reading 

parameters. 

 

 

 

The  parameters  are  active  if  the  thermoregulation  board 

manages the corresponding parameters. 

The parameters are specific of OpenTherm protocol and to 

understand the meaning is necessary to know the protocol 

OpenTherm. 

The  parameters  available,  in  different  pages,  are  the 

following: 

 
CH Temp. 

Circuit heating temperature (°C) 

Ret. Temp. 

Return water temperature (°C) 

DHW Temp. 

DHW temperature (°C) 

Out Temp. 

Outside temperature (°C) 

Exhaust T. 

Boiler exhaust temperature (°C) 

Mod. level 

Relative modulation level (%) 

CH Press. 

Water pressure in CH circuit (bar) 

DHW Flow 

Water flow rate in DHW circuit. (l/m) 

Fault flgs 

Fault flags 

Fault code 

OEM fault code 

TSP max 

Number of transparent-slave-parameters 

FHB max 

Max. dimension fault-history buffer 

Slave cfg. 

Slave configuration flags 

Slave sta. 

Slave status flags 

Master sta. 

Master status flags 

CH OT S.P. 

Control setpoint circuit heating (°C) 

Solar cfg. 

Solar configuration 

Solar sta. 

Solar status 

Storage   

Solar storage temperature (°C) 

Collector 

Solar collector temperature (°C) 

 

 

The  values  displayed  are  updated  regularly  by  the 

chrothermostat every few seconds. 

To  force  loading  you  can  press  the  middle  button 

transparent and get an instant update 

Pushing ESC instead to return to the main menu. 

 

The  second  item  on  the  "PARAMETERS  MENU"  allows 

you to send commands to the boiler. 

 

 

 

As shown in screen above, pushing the "Water filling" you 

can  load  the  hydraulic  system,  monitoring  the  pressure,  if 

the thermoregulation board manage it.  

In case of lockout of the boiler, in addition, you can send a 

request  for  remote  reset,  choosing  the  "Reset"  and  press 

ENTER. 

The remote reset is a safety function, the actual reset of the 

boiler is subject to the control of the safety logic board. 

You  can  also  unlock  the  boiler  from  the  main  screen 

(automatic  mode,  manual  mode,  etc..),  Pressing  the 

transparent button. 

 

The  third  item  concerns  of  the  transparent  parameters 

(TSP). 

This  function  depends  on  the  board  connected  to  the 

chrothermostat,  therefore,  please  refer  to  the  board's 

documentation for detailed description and the use of these 

parameters.  The  number  of  TSP  depends  of  the 

thermoregulation  board,  the  chronothermostat  supports  a 

maximum of 255 TSP (idx 001 to 255).
