Each zone on the AQUATROL network has a unique
identity (address). This address consists of a Control
Module ID and the Zone related to that controller.
• Module ID: The Boiler Controller is A, and the 1st
through 3rd Add-A-Temperature Expansion Control
Modules (i.e., AQ25400B) are B, C, and D.
• Zone: From 1 to 16 for each Module ID.
A total of four controllers (one Boiler Control Module and
up to three Add-A-Temperature Expansion Control
Modules), each having 16 associated zones can be
connected on the AQUATROL network. The AQ251
Control Panel itself can control one Boiler loop water
temperature and one secondary loop water temperature.
n/a Display only – Temperature measured by the zone
thermostat.
Target temperature set for the zone.
n/a Display only – Status is received from each zone
thermostat every 10 seconds.
Amount of temperature (number of degrees) setback from
occupied to unoccupied modes for this zone
Maximum setpoint temperature allowed for this zone's
thermostat. The SETPOINT MAX cannot be set below the
SETPOINT MIN setting.
Minimum setpoint temperature allowed for this zone's
thermostat. The SETPOINT MIN cannot be set above the
SETPOINT MAX setting.
Target HEATING temperature for the zone when system is
in VACANCY mode
Target COOLING temperature for the zone when system is
in VACANCY mode.
Only displayed when cooling is enabled for that zone.
Temperature deadband that determines the changeover
from heating to cooling and from cooling to heating:
• The thermostat switches from heating to cooling mode
when the indoor temperature is higher than the setpoint
by more than the changeover band setting for 15
minutes.
• The thermostat switches from cooling to heating mode
when the indoor temperature is lower than the setpoint
by more than the changeover band setting for 15
minutes.
Controls the zone thermostat's keyboard.
• If set to LOCK, settings cannot be changed at that
zone's thermostat.
• If set to UNLOCK, the thermostat's settings can be
changed within the respective limits.
