Notes
This ISU allows you to limit the maximum number
of times the system can cycle in a 1 hour period
measured at a 50% load. For example, when set to 3
CPH, at a 50% load, the most the system will cycle
is 3 times per hour (10 minutes on, 10 minutes off).
The system cycles less often when load conditions
are less than or greater than a 50% load. The
recommended (default) cycle rate settings are below
for each heating equipment type selected:
Hot Water Radiant Heat = 3 CPH; Hot Water
Radiant Floor Heat in A or AF mode = 1CPH; Hot
Water Radiant Floor Heat in F mode = 3CPH; Steam
= 1CPH
This ISU allows you to set minimum on time to protect
equipment from short cycling.
Adaptive Intelligent Recovery (AIR) is a comfort
setting. Heating equipment will turn on earlier,
ensuring the indoor temperature will match the
setpoint at the scheduled time.
The user cannot set the heating temperature above
this level. Air heating temperature in A/AF mode,
Floor heating temperature in F mode.
The user cannot set the heating temperature below
this level. Air heating temperature in A/AF mode.
Floor heating temperature in F mode.
This ISU is only displayed if no Wired Floor
Temperature Sensor (ISU 129) is configured.
Choose resistance type of Wired Indoor Air
Temperature Sensor. This ISU is only displayed if
Wired Indoor Air Temperature Sensor (ISU 500) is
configured.
You can choose what Air temperature source to
be used or you can ask thermostat to use both
thermostat and remote wired sensors for higher
accuracy of measurement. This ISU is only displayed
if Wired Indoor Air Temperature Sensor (ISU 500) is
configured.
*If the floor temperature is below that limit, the
heating will be activated regardless of the ambient Air
temperature. This ISU is only displayed if Temperature
Control Mode (ISU 299) is set to AF mode. The
minimum floor temp limit setting cannot be set higher
than 10 degrees below the maximum floor temp limit
setting.
