heater
8.1 Introduction
Topics covered in this chapter, in sequence:
•
Operating modes ;
• Power Anode status ;
• Error conditions
8.2 Operating modes
When running, the appliance has three basic
operating modes, namely:
•
ISOLATED
In this mode the appliance is off and all
components are electrically dead. The isolator
(switch between the appliance and the power
supply) is turned off. On the control panel:
-
The ON/OFF switch is in position 0;
- the green LED is off.
• WEEK PROGRAM (optional)
In this position the appliance only meets demand
during the periods set by the timer. Outside these
periods, only frost protection is active.
On the control panel:
-
The ON/OFF switch is in position II.
- The water temperature can be set by turning
the knob on the control thermostat, see
paragraph '5.5 Control thermostat'.
- The period during which demand must be
fulfilled can be programmed using the week
timer, see paragraph 5.6 'Weekly timer
circuit'.
- the green LED is illuminated.
Comment
If no week timer is installed, the 'II' mode is the
same as the '0' mode.
• OFF
In this mode, the frost protection is activated. The
isolator is set to position I. On the control panel:
-
the ON/OFF switch is in position 0;
- the green LED is illuminated.
• Contractor
In this mode the appliance continuously fulfils
demand. On the control panel:
-
the ON/OFF switch is in position I
- The water temperature can be set by turning
the knob on the control thermostat, see
paragraph '5.5 Control thermostat'.
- the green LED is illuminated.
8.3 Power Anode status
If the appliance is fitted with a Power Anode, there is
an extra indicator lamp on the operating panel.
Depending on the status of the appliance, this lamp
will be lit either green or red, or it will be off:
•
Green
This state indicates that the Power Anode is
working correctly.
• Red
This state indicates an error, and the Power Anode
is not working.
• Off
This state indicates that the Power Anode is not
working.
Comment
If there is an error with the Power Anode (red), or if
the Power Anode is not working (off), this will have no
effect on the hot water supply.
