This parameter is adjustable by the installer by accessing parameter I2. The time range for this parameter is 0 minutes to 40 minutes. The default time is 30 seconds.

DHW pump delay

The DHW pump delay parameter sets the length of time the DHW pump (if connected) will run after a DHW demand has been satisfied. Setting the delay time to 0 will disable the pump. This parameter is adjustable by the installer by accessing parameter I3. The time range for this parameter is 0 minutes to 40 minutes. The default time is 30 seconds.

J: Service Notification

Service notification in months

When the boiler control determines that a scheduled service is due based on days of installation, the boiler display will alternate the standard boiler display text with the message SERVICE DUE every 5 seconds. This parameter is adjustable by the installer by accessing parameter J1. The time range for this parameter is 0 months to 36 months. The default time is 12 months.

Service notification running hours

When the boiler control determines that a scheduled service is due based on the hours of actual operation, the boiler display will alternate the standard boiler display text with the message SERVICE DUE every 5 seconds. This parameter is adjustable by the installer by accessing parameter J2. The time range for this parameter is 0 hours to 100,000 hours. The default time is 10,000 hours.

Service notification boiler cycles

When the boiler control determines that a scheduled service is due based on the number of boiler cycles, the boiler display will alternate the standard boiler display text with the message SERVICE DUE every 5 seconds. This parameter is adjustable by the installer by accessing parameter J3. The range for this parameter is 0 cycles to 100,000 cycles. The default is 10,000 cycles.

Reset service notification counter
