NOTICE
i The Rinnai room thermostat and controls must be connected to their
allocated connections. All other types or makes of room thermostats or
controls which are used must have a Volt free contact.
When using an on/off thermostat or control, it may be necessary to calibrate the
anticipating resistance to prevent too high temperature fl uctuations. As a standard
rule this means mercury thermostats. This resistance wire is present in the Control
Tower and must be connected to terminals 23 and 27. The anticipating resistance in
the room thermostat has to be set at 0.11 A.
For more detailed questions regarding the components which are not supplied, the
distributor should be contacted.
When wiring an RS100 it is suggested that a jumper be placed on terminals
22 and 23 so that in the event the control is damaged the boiler will still fi re
based on outdoor reset.
A jumper should also be used when commissioning or trouble shooting the
boiler.
Power stealing thermostats cannot be connected to terminals 22 and 23.
