*1. Use a CVVS or CPEVS cable (Max. total length of 200 m) if there is a source of electrical interference near by (e.g., factory) or the total length of control
wiring exceeds 120 m.
*2. When the wiring length exceeds 10 m, use wire of 1.25 mm².
2. System Configuration
(1) Individual system
* Each unit is operated individually by connecting a dry contact switch/relay to each unit.

centralized controller (AE-200)
(2) Multiple system (2-16 units)
* A group of unit that consists of one main unit and up to 15 sub units is operated collectively by connecting an external
water temperature sensor and a dry contact switch/relay to the main unit.
