DESCRIPTION
Overview
• There are three priority levels defined by the settings
chosen in Figure 76, page 77.
• For DHW priority, make sure PRIORITY 1 is defined
for a DHW system.
• If DHW priority is required and analog input (0-10v
remote modulation) is used for space heating, wire the
DHW aquastat to Input 2 (TT2) and assign INPUT 2
as PRIORITY 1 and INPUT 1 as PRIORITY 2 with
SOURCE set to 0-10V.
INPUT 1
• Assign priority (system type) for INPUT 1 — options are:
• PRIORITY 1 — assigns INPUT 1 to PRIORITY 1 system.
• PRIORITY 2 — assigns INPUT 1 to PRIORITY 2 system
• PRIORITY 3 — assigns INPUT 1 to PRIORITY 3 system
• AUX PUMP/OUTPUT
• OFF
• NOTE: For INPUT 1 only, select SOURCE = TT1 for
thermostat input or 0-10V if analog input is required.
INPUT 2
• Assign priority (system type) for INPUT 2 — options are:
• PRIORITY 1 — assigns INPUT 2 to PRIORITY 1 system.
