Vessel
You can operate the 2-zone control using a mixing value, water-out temperature sensors, and built-in or external room
temperature sensors installed in a wired remote controller .
When both zones are simultaneously Thermo on, the operation is performed based on Zone2 . Therefore, set the zone that
you want to have the higher set temperature to Zone2 .
(The mixing valve must be installed in the zone that you want to have the lower set temperature . )
1 . Install the mixing valve . (See "Installation of mixing valve . " )
2 . Install the water-out temperature sensors (Tw2_z1, Tw2_z2) for all zones .
3 . Unlike the zone control with a thermostat, connect the water pump signal lines to the product .
f Zone1 water pump connection: B10 (L1) + B11 (N)
f
f Zone2 water pump connection: B14 (L1) + B15 (N)

4 . FSV 4061 = 1: Enable the 2-zone control using the wired remote controller .
* If you want to operate the 2-zone control by using water-out temperatures, you have only to complete steps 1 to 4 above .
* If you want to operate the 2-zone control by using room temperatures and built-in temperature sensors in wired remote
controllers, you must install two wired remote controllers in each room .
(If you use external room temperature sensors, you can control each room temperature with only one wired remote
controller . )
