To Prestige
Fig. 21: Secondary System Circulator Wiring
When making low voltage connections to
the Prestige, ensure no external voltage
is present in the thermostat circuits. If
external voltage is present, provide an
isolated contact to prevent damage to
the boiler control.
CH and DHW Circulator
1. Connect the CH primary circulator to the
PRESTIGE Solo 120 V terminals 1,2 and 3
as shown in Fig. 20, page 32.
2. Connect the DHW circulator to the PRES-
TIGE Solo 120 V terminals 4, 5 and 6 as
shown in Fig. 20, page 32.
3. Maximum circulator continuous current
draw is 2A for each circulator.
System Circulator - Zone Valve Application
To energize the system circulator shown as
item 12 in Fig. 10 page 21 reference Fig. 21.
Installer to provide a Transformer / Relay such
as Honeywell R8285 or equivalent and Zone
Valves with isolated end switch such as
Honeywell V8043 or equivalent.
External Modulating Control
The PRESTIGE Solo firing rate can be con-
trolled by an external modulating boiler con-
troller. See page 32 for wiring and Page 54 for
control module setup.
Outdoor Reset Control
The PRESTIGE Solo may operate with a vari-
able boiler operating temperature using the
Triangle Tube outdoor sensor, see pages 50
through 53 for installation and set-up.
If the installer opts for a fixed operating
temperature for the boiler system, the
outdoor sensor is not required and
should not be installed.
Additional 24V Limit Wiring
The PRESTIGE Solo provides 24V terminal
connections for additional limit controls as
shown in Fig. 20 page 32. These limit terminal
connections will provide a "hard" lockout
requiring a manual reset of the PRESTIGE
Solo control, or a “soft” lockout in which the
PRESTIGE Solo will automatically reset.
