MINI MERLIN CH4CO
Appliance Limit Circuit
The device can be used to directly shut down a gas appliance when a
fault condition is detected (gas leak), by wiring the
normally closed (NC) and common (COM)
terminals of the low volt BMS switches into
the low voltage safety limit circuit of the
appliance.
If gas is detected, the limit circuit is opened, disabling the appliance.
Multiple Appliance Limit Circuit
The device can be used directly to disable multiple gas
appliances when a fault condition is detected (gas leak) by
wiring a multi-pole relay to the GAS VALVE LINE terminal.
Low voltage wiring is to be inserted into the external limit
circuit of a gas appliance.
The Honeywell Relay has a 120vAC primary coil with two sets of switches, each with Normally
Open (NO) and Normally Closed (NC) contacts.
These contacts are rated for up to 12A AFL. They can be used to break either a low or line volt
limit circuits or completely remove power to an appliance.
