A remote two-channel programmer
must be suitable for 230 V and
internally linked - for example, use
the Grant Type ESKIT programmer.
Connect the switched live output from
the Hot Water channel of the
programmer (DHW ON terminal) to
terminal L2 of the boiler isolation plug.
Refer to Figure 8-5.
Connect the switched live output from
the Heating channel of the programmer
(CH ON terminal) to terminal L1 of the
boiler isolation plug, via the room
thermostat. Refer to Figure 8-5.
Connect the mains supply to the boiler
isolation plug as follows (refer to Figure
8-5):
• Permanent live to terminal L3
• Neutral to terminal N
• Earth to earth terminal
If an alternative two-channel
programmer to the Grant ESKIT is to be
used, it must be suitable for 230 V and
internally linked. Refer to Figure 8-5 for
connection details.
Re-connect the electrical supply and
check the operation of the programmer

Refer to the Fitting & User instructions
provided for with the programmer for
operating and setting.
