• B4 - Oil Boiler Hysteresis – 2nd Stage (relay R2)
Set this as parameter C51 for the 2 nd stage on the Oil Boiler Control
Thermostat.
The factory default value for parameter C51 is +3°C. This must be
checked and re-set, if required, to give the required parameter C51
value (B4) as indicated by the calculator.
Refer to Section 16.5.1 for guidance on setting parameter C51 on
the Oil Boiler Control Thermostat.
•
A1 - Air Thermostat Temperature – 1st Stage (relay R1)
Set this as parameter SP for the 1
st
stage on the Air Control
Thermostat.
The factory default value for parameter SP is 9°C. This must be
checked and re-set, if required, to give the required parameter SP
value (A1) as indicated by the calculator.
Refer to Section 16.5.2 for guidance on setting parameter SP on the
Air Control Thermostat.
•
A2 - Air Thermostat Hysteresis – 1st Stage (relay R1)
Set this as parameter C1 for the 1
st
stage on the Air Control
Thermostat.
The factory default value for parameter C1 is +3°C. This must be
checked and re-set, if required, to give the required parameter C1
value (A2) as indicated by the calculator.
Refer to Section 16.5.2 for guidance on setting parameter C1 on the
Air Control Thermostat.
•
A3 - Air Thermostat Temperature – 2nd Stage (relay R2)
Set this as parameter SP2 for the 2
nd
stage on the Air Control
Thermostat.
The factory default value for SP2 is 1°C. This must be checked and
re-set, if required, to give the required parameter SP2 value (A3) as
indicated by the calculator.
Refer to Section 16.5.2 for guidance on setting parameter SP2 on
the Air Control Thermostat.
•
A4 - Air Thermostat Hysteresis – 2nd Stage (relay R2)
Set this as parameter C53 for the 2
nd
stage (R2) on the Air Control
Thermostat.
The factory default value for parameter C53 is +3°C. This must be
checked and re-set, if required, to give the required parameter C53
value (A4) as indicated by the calculator.
Refer to Section 16.5.2 for guidance on setting parameter C53 on
the Air Control Thermostat.
16.5 Digital Temperature controllers
There are two digital temperature controllers on the Hybrid unit
control panel:
•
The Boiler Control Thermostat
•
The Air Control Thermostat
Refer to Figure 14-3 – control panel to locate the two digital
temperature controllers.
Whilst the procedure for setting each digital controller is the same,
the temperature values set on each controller are different. It is
essential that the correct values are set on each controller.

Figure 16-1: Digital temperature controller
There are FOUR buttons on the controller keypad. Their functions
are as follows:
•
ESC
Deactivates alarms but they remain signalled (According to
parameter A16).
The save without changes, return to previous level or exit
programming parameter appears on the programming menu.
•
SET
Pressing it for 5 seconds allows changing the SP set point of
relay 1.
Pressing it for 10 seconds accesses the programming menu.
In the programming menu, it accesses the level shown on the
display or, during the setting of a parameter accepts the new
value.
•
Up
Pressing it for 5 seconds allows changing the SP2 set point of
relay 2.
In the programming menu it allows scrolling around the
different levels, or during the setting of a parameter, changing
its value.
•
Down
Pressing it for 5 seconds activates the Stand-by mode and
pressing if for 2 seconds returns the device to the normal
mode. In the Stand-by mode, the unit does not carry out any
action and the display only shows the m indicator.
In the programming menu it allows scrolling around the
different levels, or during the setting of a parameter,
