Bottom Blowdown Valve.
Connect the Bottom Blowdown valve per the electrical drawing. A controller in the control panel
will then allow automatic bottom blowdown to occur on a time basis. The contact gives feedback
to the controller that the blowdown valve has opened and closed as required (Valve supply Max.
rating 120V 6A resistive, 120V 2A inductive. Valve switch contact rating 230V 10A Max.).
TDS Solenoid Valve.
Connect the TDS Solenoid valve per the electrical drawing. A controller in the control panel will
then allow automatic TDS blowdown to occur as required by monitoring the TDS in the boiler
(Valve supply Max. rating 120V 6A resistive, 120V 2A inductive).
Fan Dilution Pressure Switch.
Depending on the installation, a Flue dilution system and/or a plant room ventilation system may
be required. These are safety features to prevent a high contamination of flue gasses in the
system. Pressure switches are fitted within the systems to ensure that the required fans are
running, hence diluting the flue gasses. If the fans fail, a pressure switch will operate to stop the
boiler and prevent further contamination occurring. A factory fitted link must be removed to use
this option (110V).
Remote Alarm Panel.
A remote alarm panel to suit 1, 2 or 3 boilers can be fitted in a manned area. The panel will give
an indication of a boiler alarm being triggered and also has the ability to remotely stop the
individual boilers.
Water softener.
A water softener can be powered from the boiler control panel (230V, 2A Max.).
Feed Tank Level Control.
A Feed tank level control panel can be powered from the boiler control panel. It controls the level
of feedwater in the feedwater tank if fitted (110V, 4A Max.). In the case of multiple, this panel
must be fed from an independent suitable supply.
Feed Line Chemical Dosing.
A Feed line chemical dosing unit must be powered from a local fused spur supply (110V, 4A Max.).
