Follow boiler manual

1.  Follow all procedures in the

Gas boiler manual

to start up and verify operation of the boiler.

Set space heating operation

1.  Press  the “Mode”  button  until  the  display  shows

“Para.” This is the parameter mode.

2.  Press the “Step” button until the display first digit

shows “.”

.  The last digit must show “1.” If any other number

displays, press the “+” button until “1” shows in the

right-hand digit. Press the “Store” button to save

this setting.

1.  Press the

control panel “Step” button until

the display first digit shows “.” The right  digits

show the outlet water temperature setting.

2.  Press the “+” or “-” button to change the setting to

the desired outlet water temperature. (The factory

default setting is 190 °F.)

a.  Outdoor  sensor  installed  —  Setting  is  the  target

temperature  for  outdoor  temperature  at  or  below
2 °F. At higher outside temperatures, the

PhD

control module calculates the target temperature. (See

Control Supplement for detailed discussion of

outdoor reset.)

 When  a  summer/winter  switch  is  used,  closing  the

switch will disable the boiler (space heating) circulator
during summer operation.

b.  Outdoor sensor not installed — Setting is the target

temperature at all times.

.  Press the “Store” button to save the setting.

Water heater operation

1.  The PLUS water heater thermostat must be con-

nected  to  low  voltage  terminal  strip  terminals 

and  as shown on page 10.

2.  When the water heater thermostat calls for heat,

the module shuts down the boiler circulator, acti-

vates the water heater circulator and immediately

sets target outlet water temperature to 190°F. This

provides automatic priority heat allocation to the

indirect water heater for maximum response and

recovery.

.  The water heater circulator continues for 0 seconds

after the heating cycle to deliver the most possible

heat.

Water heater operation setup

1.  Go to step 2 if the control is in Parameter mode

already. Press the “Mode” button until the display

shows “Para” (parameter mode).

2.  Press the “Step” button until the display first digit

shows “2.”

.  The last digit must show “1.” If any other number

displays, press the “+” button until “1” shows in the

right-hand digit. Press the “Store” button to save

this setting.

.  The

PhD control module turns on the PLUS

circulator when the indirect water heater operating

control  closes.  The  control  module  shuts  off  the

boiler circulator (stops space heating) during calls

for DHW heating.

Verify space heating operation

NOTE: “[  _  _  _  _  ]”  in  the  following  indicates  the

characters that should show on the

display panel.

“180” in the right  places means the display shows the

measured boiler water temperature. The number shown

will not necessarily be 180.
1.  Turn  down  aquastat  on  PLUS  tank.  If  necessary,

turn off power and remove one of the PLUS aqua-

stat wires to ensure boiler will not receive a DHW

heat call.

2.  Turn off power to boiler at service switch.
.  Wait a few seconds, then turn on power to boiler.

[

A180] (self-check on power-up, for a few seconds)

[

0180] (no call for heat)

.  Raise room thermostat to call for heat.

[

5180] (blower/circulator on) The blower and boiler circu-

lator energize and the control checks for air flow.

[

1180] (prepurge) After a few seconds delay (control self-

check), blower speed will increase to ignition speed.
The blower will run in prepurge for 10 seconds.

[

2180] (ignition) After prepurge, the control module

opens the gas valve and starts ignition spark.

a.  If burner flame proves within . seconds, burner

continues  to  fire.  Burner  will  fire  at  start-up
rate — 0% of maximum input — for about 10
seconds to allow flame to stabilize.

b.  If burner flame does not prove within . sec-

onds, control module attempts ignition sequence
again. Flame must prove within  attempts or
control will lockout (display will show [

E  02]).

c.  Verify flame failure operation by closing boiler

manual  gas  cock  to  prevent  gas  flow.  Open
manual gas valve after testing.
