Mixing Valve
The mixing valve is controlled based on the FCU WL value.
As the #4044 value increases and the #4045 value decreases, the control speed increases. (Temperature hunting may
occur if the control speed increases depending on the load.)
The additional pump and mixing valve should be purchased separately. TW4 sensor is included in the product
accessories.
TW3 : Water temp. sensor 3
• When the thermostat control is set as 'Use', the mixing valve can be used for Zone 1 and Zone 2. (When both FSV
#2091 and #2092 are set as 1/2)
• When using Zone control (FSV 4061 = 1), ignore Thermostat signal.
