AQ25A SERIES PROGRAMMABLE BOILER CONTROL PANELS
Energizes / de-energizes the line voltage terminals marked
Boiler when switched to ON / OFF respectively.
Closes / opens the line voltage rated dry contacts marked
Aux. when switched to ON / OFF, respectively.
Energizes / de-energizes the line voltage rated terminals
marked DHW when switched to ON / OFF respectively.
Closes / opens the low voltage rated dry contacts (terminals
17 and 18) marked Boiler T-T when switched to ON / OFF
respectively.
Closes / opens the low voltage rated dry contacts (terminals
19 and 20) marked Aux. Out. when switched to ON / OFF
respectively.
Produces voltage on the 10 Vdc low voltage terminals (15
and 16), according to the setting chosen (0V to 10V), in
increments of 1V.
Displays the temperature measured by the outdoor sensor.
"- -" means sensor is disconnected
LO means temperature reading is below -55°F (-50°C)
HI means temperature reading is above 212°F (100°C)
Displays the temperature measured by the boiler supply
sensor.
"- -" means sensor is disconnected
LO means temperature reading is below -49°F (-45°C)
HI means temperature reading is above 257°F (125°C)
Displays the temperature measured by the Return/DHW
sensor.
"- -" means sensor is disconnected
LO means temperature reading is below -49°F (-45°C)
HI means temperature reading is above 257°F (125°C)
Does not display when the RETURN/DHW sensor is
configured as a DHW sensor.
Displays the temperature measured by the sensor
configured for DHW (the sensor wired to the Return/DHW
terminals 5 and 6).
"- -" means sensor is disconnected
LO means temperature reading is below -49°F (-45°C)
HI means temperature reading is above 257°F (125°C)
Displays only when the sensor is configured as a DHW
sensor.
