NOTE: The 230V switched signal for external controls (Frost Stat - Room Stat - Timer) must always be taken from terminal 2 at the boiler. Live, Neutral and Earth to power these controls must be taken from the Fused Spur.

10.0Installation

10.7Making The Electrical Connections

NOTE: Both the Live and Neutral connections are fused.

To connect an external control proceed as follows:-

1.Slacken the facia panel securing screws and lift the outercase panel so that its securing tabs are clear of the facia. Remove the panel.

2.Completely undo the screws securing the facia panel and hinge it down (Fig. 55).

3.Undo the terminal block cover securing screw and remove the cover (Fig. 55).

4.Slacken the unused cable clamp on the LH side of the boiler chassis (Fig. 56). Insert the external control wiring through the clamp and route it to the terminal block.

5.Refer to the instructions supplied with the control.

IMPORTANT: The room thermostat MUST be suitable for 230V switching.

NOTE: An external frost thermostat cannot be used with the optional integral timer.

6.Remove the link between terminals 1 & 2. The 230V supply at terminal 2 must be connected to the thermostat. The switched output from the thermostat must be connected to terminal 1 (Fig. 57). If the room thermostat being used incorporates an anticipator it MUST be wired as shown in Fig. 57.

7.Ensure that the external control input cable(s) have sufficient slack to allow the control box to drop down. Tighten the cable clamp on the boiler chassis.

8.Replace the terminal block cover, routing the external control input cable(s) through the second cut-out.

10.8Preliminary Electrical Checks

1.Prior to commissioning the boiler preliminary electrical system checks should be carried out.

2.These should be performed using a suitable meter, and include checks for Earth Continuity,

Resistance to Earth, Short Circuit and Polarity.
