AQ252 Universal Injection/Mixing Boiler Reset Control Panels
Description
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 secondary
mixed water 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.
Sequentially energizes / de-energizes all zones connected
to the AQUATROL network.
• 0 displays when the Control Module has confirmation
that the pump/valve is closed.
• 1 displays when the Control Module has confirmation
that the pump/valve is fully open.
In the case of pump zoning, the 1 displays no more than 5
seconds after the activation of the relay. In the case of valve
zoning, the 1 displays either when the zone valve operating
time (defined in EQUIPMENT SETUP > ZONING > ZONE
VALVES TIME TO OPEN) has elapsed (AQ15540B) or
when the valve's end switch is closed (AQ15740B).
Energizes / de-energizes each zone individually.
• 0 displays when the Control Module has confirmation
that the pump/valve is closed.
• 1 displays when the Control Module has confirmation
that the pump/valve is fully open.
