Wiring a system circulator

1.For combined systems, to activate a system circu- lator when the Boiler circulator operates, wire as shown at bottom of Figure 17, page 30.

2.You must install a relay as shown. DO NOT wire in parallel with the Boiler circulator. See CAUTION in Figure 17.

4.Install a summer/winter switch (Figure 19, item 7) across terminals 1 and 2 to force fixed-temperature operation during summer months. (When the switch is closed, boiler will attempt to maintain constant temperature.)

5.Route sensor wires through the grommeted hole at right of the electrical entrance (see Figure 18).

Routing line voltage wiring

1.Route line voltage connections to the jacket open- ings shown in Figure 18.

Water heater thermostat

1.Connect PLUS water heater aquastat terminals

“C” and “1” to Gas boiler low voltage ter- minal strip between terminals 3 and 4 (Figure 9, item 3).

Low voltage connections

(Fig. 18)

1.Connect low voltage wiring to low voltage termi- nal strip (Figure 19, page 32, item 1) as shown in Figure 19 and the boiler wiring diagram.

2.Route all low voltage wires through grommeted jacket opening to right of low voltage terminal strip, as shown in Figure 18.

Room thermostat (space heating)

1.For combined space heating/water heating systems, connect Figure 19, item 2, room thermostat or end switch (isolated contact only) between terminals 5 and 6.

2.Install thermostat on inside wall away from influ- ences of drafts, hot or cold water pipes, lighting fixtures, television, sunrays, or fireplaces.

3.Thermostat anticipator (if applicable):

a.If connected directly to boiler, set for 0.1 amps.

b.If connected to relays or other devices, set to match total electrical power requirements of connected devices. See device manufacturers’ specifications and thermostat instructions for details.

Outdoor temperature sensor

1.Outdoor reset operation applies only to combined space heating/water heating systems.

2.Connect outdoor temperature sensor (Figure 19, item 6) between terminals 1 and 2 to enable out-

door reset operation of the Gasboiler. If fixed-temperature operation is required, do not install outdoor sensor.

3.Mount sensor on exterior wall, shielded from di- rect sunlight or flow of heat or cooling from other sources.

Additional limits

1.Connect additional limit controls and interlocks between the terminals shown in Figure 19.

2.Controls connected between terminals 6 and 7 (see Figure 19, item 4) will cause a soft lockout (automatic reset). When limit(s) closes, boiler will resume normal operation.

3.Controls connected between terminals 6 and 8 (see Figure 19, item 5). will cause a hard lockout (manual reset). The boiler will only restart after the Ultra display panel RESET switch is pressed.
