Demand Type allows the installer to select the type of device which will
generate a domestic hot water call. Press the

select the DHW Demand Type then press the oK button to store the set-

• Switch - A domestic hot water call from an aquastat or dry contact
switch will enable the Prestige with a fixed setpoint for a domestic
hot water call.
• Sensor - This option requires the use of Indirect Water Heater Sensor
PSRKIT22 which is included with every PRESTIGE Solo. The
PRESTIGE Excellence utilizes an Indirect Water Heater Sensor. The
Prestige will monitor the DHW storage temperature and generate a
domestic hot water call when the temperature drops below the DHW
Storage Setpoint - DHW On Differential.
