Product Information
2.6.1 Method 1 — Zone Control via Power Level
Zone temperature control via power levels is suitable for areas
< 64 sq. ft. 2 where a thermostat is not used. The power level operation
method monitors the temperature difference between the supply
temperature and the return temperature on the respective circuit. Each
power level represents a 2° F differential.
Power Level Return Temp = Supply Temp Minus
Power Level 1 20° F
Power Level 2 18° F
Power Level 3 16° F
Power Level 4 14° F
Power Level 5 12° F
Power Level 6 10° F
Power Level 7 8° F
Power Level 8 6° F
Power Level 9 4° F
Power Level 10 2° F
The power level can be set using the button on a circuit hub or via the
operation software.
See
Ä
4.2 “Method 1 – Zone Control via Power Level” on page 45 to
learn how to set the power level on a circuit.
2.6.2 Method 2 — Zone Control via Thermostat
When the zone temperature is controlled with a thermostat, the control
unit achieves the desired zone temperature (target temperature) by
pulsing the powerhead of the respective circuit(s). The following inputs
are used to determine the pulsing output parameters: actual room
temperature, target temperature, supply temperature, the circuit(s) return
temperature(s) associated with that zone, and the return temperatures
on unassociated circuits.
Circuit(s) are assigned to thermostat(s) during thermostat set-up.
