board, then select ANALOG INPUT 6 and select Extra Controller Temperature Sensor (ECT) from the input
type list.
10.3.2 Duct water heater
A duct water heating battery is supposed to be installed in supply air duct.
• WH — water heating battery
• FPT — frost protection sensor
• SAT — supply air temperature sensor
• S — actuator for valve
• 1 — Outdoor air
• 2 — Supply air
• 3 — Extract air
• 4 — Exhaust air
Component/product — Article number:
• VAZ4 24A Actuator 0-10V (S) — 9862
• Duct sensor -30-70C (SAT) — 211524
• Surface sensor -30-150C (FPT) — 211523
• VSR 300:
VBC 160-2 Water heating battery— 5458
VBC 160-3 Water heating battery — 9840
ZTV 15-0,4 2-way valve — 9829
ZTV 15-0,6 2-way valve — 6571
ZTR 15-0,4 valve 3-way — 9670
ZTR 15-0,6 valve 3-way — 6573
• VSR 500:
VBC 200-2 Water heating battery— 5459
VBC 200-3 Water heating battery — 9841
ZTV 15-0,6 2-way valve — 6571
ZTV 15-1,0 2-way valve — 9823
ZTR 15-0,6 valve 3-way — 6573
ZTR 15-1,0 valve 3-way — 6572
Installation and connection
1. Install water heater in the duct. Connect pipes, 2/3–way valve and actuator.
Important
Do NOT use 24V DC power output from the connection board for valve actuator.
2. Connect actuator (S) to any free analog output.
3. The frost protection sensor (FPT) should be strapped on a surface on the return water pipe. Connect FPT sensor to
any free analog input.
4. Internal supply air temperature sensor (SAT, default connection AI2 on the main circuit board) must be replaced by a
duct temperature sensor which can be acquired as an accessory. A duct temperature sensor must be installed in the
duct after water heater: Connect duct temperature sensor in a place of internal supply air temperature sensor (AI2).
