HIGH TEMP Illuminates

when the boiler water tempera-

ture reaches the high limit set-

ting. It will remain lit until the

water temperature falls 10°. The

Fuel Smart HydroStat prevents

burner operation while this LED

is on.

LWCO ACTIVE Indicates that the low water cut-off (LWCO)

function of the Fuel Smart HydroStat is active. When the control is

installed with a Hydrolevel Electro-Well, this LED will be on at all

times when the control is powered. IMPORTANT: If the control is

installed with a well other than the Electro-Well, this LED will not

illuminate indicating that the control is not providing low water cut-

off functionality.

w LWCO LOW WATER Illuminates if the boiler is in a low water

condition. The Fuel Smart HydroStat will prevent burner operation

during this condition. IMPORTANT: The system must be checked

by a qualified heating professional prior to resuming operation.

WARNING: DO NOT ADD WATER UNTIL THE BOILER

HAS FULLY COOLED.

❹ ECONOMY ACTIVE Indicates that the Thermal Targeting

function is active and the Fuel Smart HydroStat will reduce boiler

temperature to conserve fuel. The Economy feature is activated

using the ECONOMY dial. (See “How Thermal Targeting Works” for

more information).

❺ECONOMY TARGET When the Economy feature is active, the

Fuel Smart HydroStat continually sets target temperatures below

the high limit setting to maximize fuel efficiency. When the boiler

water reaches the target temperature, the LED illuminates and the

burner will shut down. The boiler water will continue to circulate and

heat the house as long as the thermostat call continues. The LED

will stay lit until the boiler temperature drops to the differential set

point (see Differentials) at which point the boiler will be allowed to

fire again. NOTE: This LED illuminates regularly during normal boil-

er operation.

➏ PURGE The control is purging latent heat from the boiler and

will not fire until the temperature drops to 135˚F. See Thermal Pre-

Purge section.

❼ LWCO TEST BUTTON

To Test Low Water Cut-Off: Press and hold the LWCO TEST

button. The red Low Water light should illuminate and the burner cir-

cuit should de-energize. NOTE: The control must be installed with

a Hydrolevel Electro-Well for low water cut-off functionality.

INDIRECT EXTERNAL WATER HEATER CONNECTIONS

If system includes indirect water heater, the indirect signal must be

separated from heating zone(s) system. See figure 15 ans 16.

a. Connect end switch of the indirect water heater relay to the

terminal block of the boiler marked “DHW End Switch Relay.”

b. Connect end switch of the heating zone(s) relay(s) to the

thermostat terminal block.

c. Remove P5 connector from the boiler control. Disconnect and

remove wires connected to the boiler circulator. See figure 2, 13a

and 13b.

d. Power DHW and heating zone(s) circulators through end switch

relays as shown on figure 15 and 16.

WATER PIPING

Always follow good piping practices. Observe minimum 1" clearance

to combustibles around all uninsulated hot water pipes or when open-

ings around pipes are not protected by non-combustible materials.

On a hot water boiler installed above radiation level, the boiler must

be provided with a low water cutoff device at the the time of installa-

tion by the installer (see Figure 17 for piping arrangement).

The low water cutoff must be wired in series with rollout safety switch

and Aquastat (limit control). See wiring diagram Figure 13a.

1. Supply and Return

For tapping sizes see dimensions on page 2. Shut-off valves are

recommended.

2. Circulating Systems

Victory VSPH boilers are equipped with a water circulating

pump mounted to the return water connection on the boiler. This

pump location is appropriate for most installations. It may be

desired and proper to locate this pump to the alternate location

shown in Figure 17, especially when applied to larger systems

using high-head pumps. When the pump is removed there is a

⁄2" FPT tapping that the return pipe may be attached to.

At one month intervals after the last call for heat, the circulator

will be energized for 30 seconds. Short operation after long term

idle periods prevent damage of the pump from sedimentation.

3. Radiant Floor, Low Water Temperature and large water

volume systems

A boiler by-pass loop, three way valve arrangement, or primary

secondary pumping (with a boiler loop) must be used to provide

a minumum 130˚ return water temperature to the boiler. This will

prevent condensation on the cast-iron sections that can result in

improper operation of the boiler.

MULTI ZONING

For multiple zoning, either zone valves or circulators maybe used.

For zone valve system see Figure 14.

For pump zoning system see Figure 15 and Figure 16.

DO NOT use boiler transformer to power external accessories like zone

valve and relays, overload and/or burned-out transformer and boiler mal-

function can result. Use separate transformer to power such components.

For pump zoning system, remove boiler circulator wire connector from P5

of electronic boiler control (See Figure 13b).
