Battery Replacement

A 3V coin style lithium battery with part number CR2450N is installed in every ModSync screen. The battery is
responsible for the backup of the program, system data, and user settings. It is recommended that the battery be
replaced every 3-5 years to prevent issues such as loss of program or customer settings.

Explanation / Recommended Action
The ModSync is active and no alarms are sensed.
The Outdoor Sensor is providing a value that is outside of the allowable scale. Verify
the RTD wiring, replace the sensor if necessary.
The Hydronic Loop Sensor is providing a value that is outside of the allowable scale.
Verify the RTD wiring, replace the sensor if necessary.
The Local boiler controls have indicated that an alarm condition occurred.
The ModSync called for the boiler to start and the main gas valve inputs was not
received within a customer adjustable 5 minutes. Check the limit string of the boiler
to verify which device is preventing the boiler from enabling. Verify the operating
limits are set higher than the maximum loop temperature variable on the ModSync.
Issues with the Modbus communication between the ModSync and the specified
boiler. Check wiring and local boiler control settings. See section 4 of this manual for
local boiler control setup and addressing.
