Reset Switch
The reset switches of the Chillgard RT Relay Module and controlling

switch on the Refrigerant Monitor does not affect the Relay Module
horn, and pressing the reset switch on the Relay Module does not affect
the Refrigerant Monitor horn. If the Chillgard RT Relay Module reset
switch has been used to silence the Relay Module horn, and any alarm
condition (configured to activate the horn) occurs at a new sequencer
point, t
he horn relay will activate to signal the new alarm condition.
Maintenance
Under normal operating conditions, the Chillgard RT Relay Module
requires no maintenance. However, periodic testing of the relays may
be done to ensure that complete system operation is possible.
