Inverter Pump
(FSV 40**)
• FSV #4051 = 1 (Default) : Inverter pump use + Output 100%
• FSV #4051 = 2 : Inverter pump use + Output 70%*
• FSV #4051 = 0 : Inverter pump not use.
• FSV #4052 is for adjusting temperature difference between Tw2 and Tw1.
* Too high flow is a design issue which must be rectified via balancing valves or regulation valves. Reducing max PWM
output results in reduced control possibility for the PWM pump. See section 6.1 Flow Rate, for flow rate information.
NOTE
• Tw1 (Inlet Water Temp.), Tw2 (Discharge Water Temp.), Tw3 (Backup Heater oulet Water Temp.),
Tw4 (Mixing valve Temp.).
6) Zone Control (Field Option)

Zone Control
(FSV 40**)
• FSV # 4061 should be set to "1 (Yes)" to enable zone control via the wired remote controller.
– To use the zone control (FSV #4016 = 1), set the thermostat control option (FSV #2091 & #2092) to "0" to disable
external thermostat control.
– This field option controls two zones (Zone 1, Zone 2) via application of the wired remote controller as a room sensor,
not by using an external room thermostat signal.
NOTE
• MIM-E03CN (MONO Control Kit) model does not support this zone control function.
• MIM-E03EN (MONO Control Kit) model does support this zone control function.
• The upper-level controllers excluding Wi-Fi kit (2.0) and MWR-WW10** wired remote controller cannot
use the 2-zone control and energy monitoring.
• When connecting between the MWR-WW10** wired remote controller and an upper-level controller,
the settings for FSV (#4061) must be changed not to use the 2-zone control.
