Инструкции По Установке для Utica Boilers SSV

A.  Provided with boiler.

B.  Locate outdoor sensor to protect against wind and 

direct sunlight. Mounting instructions provided with 

sensor. 

C.  Maximum wire length is 100 ft (30m) for 22 ga. 

wire, or 150 ft (45m) for 18 ga. wire.

D.  Connect wires to OUTDOOR SENSOR terminals. 

Wires are interchangeable.

A.  Use temperature control with dry contacts rated 

at 0.5 amps @ 120 VAC. Boiler control does not 

provide power to DHW temperature control. 

IMPORTANT: Do not apply power to DHW T-T 

terminals.  Dry contact only, use of isolation relay 

may be necessary.

B.  Maximum wire length is 330 ft (100m) 22 gauge wire.

C.  Connect wires (interchangeable) to DHW T-T 

terminals. Wires are interchangeable.

A.  Use thermostat or boiler system control with dry 

contacts related 0.5 amps @ 120 VAC.

 

Boiler control 

does not provide 24 VAC power to central heating 

thermostat.

B.  Locate and install thermostat per manufacturer's 

instructions. Maximum wire length is

 

330 ft (100m) for 

22 ga. wire.

C.  Connect wires to CH T-T terminals. Wires are 

interchangeable.

Connect LWCO switch leads to terminals provided. See 

Figures 14.1 thru 14.4 for wiring diagrams. Provide 

power to LWCO per manufacturer's instructions. 

Boiler transformer does not have adequate VA to 

power accessories, including LWCO.

Use dry contact for wires to CH T-T terminal and  

DHW T-T terminal. E33 error code is displayed if 

voltage is sent back to the control board. If error 

is not corrected for extended period of time, this 

voltage can permanently damage control board.
