Setting The Boiler Parameters
Parameter mode
To access PARAMETER mode when the sys-
tem is in STANDBY mode, press the MODE
button once.
To scroll through the list of parameters, simply
press the “STEP” button. To modify a parame-
ter value, use the + or - keys. Then press
“STORE” to save the value you just changed.
The display flashes once to confirm the data
has been stored.
To activate the parameters you changed, press
MODE once more (which brings you into
INFORMATION mode). However, if you do
not press a key, the system returns to STAND-
BY mode after 20 minutes and automatically
stores the changes.
Note 1: This parameter is factory set to 140ºF.
It is important to note the control adds 46ºF to
this setting, therefore the actual domestic hot
water boiler setpoint is 140ºF + 46ºF = 186ºF.
Note 2: This parameter should not be changed
from the factory setting of 01. The perfor-
mance of the DHW will be affected and can
become unreliable.
Note 3: This parameter should not be changed
from the factory setting of 01. The perfor-
mance of the CH (Central/Space Heating) will
be affected and can become unreliable.
Accessing Boiler Information
Information mode
To switch from STANDBY mode to INFOR-
MATION mode, press MODE twice.
Press STEP until the system displays the infor-
mation you need. The point located behind the
first position flashes to indicate that the boiler
is in INFO mode.
