<ZONE1>
• An operation starts at the set temperature of straight -line approximation for the following: water temperature A°C with the outside
temperature T0°C, B°C with T1°C, C°C with T2°C, D°C with T3°C, and E°C with 20°C.
<ZONE2>
• Set temperature of the ZONE2 can be selected from two methods (DN_A2). One is a percentage of ZONE1, the other is a fixed value.
DN_A2 = "0" : Percentage method that is set by DN_31.
DN_A2 = "1" : Fixed value method that is set by DN_A3, A4 and A5.
However, it is automatically controlled the set temperature of ZONE1 to be the ZONE2 or more.

ZONE 2
80% (DN_31) of ZONE1
Auto-Curve in ZONE2 shows 80% (DN) of that of ZONE1, the
water temperature setting does not fall below 20°C.
The ZONE2 set temperature A'°C with the outside
temperature T0°C, B'°C with T1°C, E'°C with 20°C.
