Commissioning
Fill the system by introducing water to both primary and
secondary circuits in turn, all pipework vents should be
open to allow air to escape freely. Ensure all air is
removed from pump/s by venting pump casing.
NOTE:
Never run pumps dry.
P.I.D. Digital Controller
Set desired water temperature (normally 60
?
C by
pressing the F key, this will cause the upper display to
show set point and lower display will read SP, press the
raise/lower keys to set desired temperature, press the F
key once more to return to the normal display. If there is
no key activity within 1 minute the display will
automatically return to normal. Units with dual set point
facility should be set as follows:
1.
Press the F key, this will cause the upper
display to show set point 1 and the lower display
will read SP1.
2.
Press the raise/lower keys to set desired
temperature.
3.
Press the F key again and the upper display will
show set point 2 and the lower display will read
SP2, set the desired temperature for set point 2
as above.
4.
Press the F key once more to return to the
normal display. Under normal running
conditions the upper display will show actual
temperature and lower display will show desired
temperature.
5.
To close/open the valve manually press the
HAND key, and the display will read actual
temperature in the upper display and P in the
lower display, the SET indicator will also flash.
6.
Press the raise key and the valve will move
towards the open position.
7.
Press the lower key and the valve will move
towards the closed position.
8.
Press the HAND key to return to normal display.
All other parameters have been factory set, no
attempt should be made to alter these without
consulting Armstrong Holden Brooke Pullen.
Dual Set Back Time Clock (if fitted)
Set the time clock so that the ON periods represent set
back times (set point 2).
24 hour model: Turn dial so correct time coincides with
the white triangle.
7 day model: Turn dial so correct time and day coincides
with the white triangle.
Both models are complete with battery back up.
The red and blue pins are inserted in the dial rim as
required. A red pin marked 1 gives an ON operation,
and a blue pin marked 0 gives an OFF operation. Both
models have a manual override switch; 1 = ON, 0 =
OFF.
High Temperature Alarm
Set the high temperature sensor (normally 12
?
C above
set point) by adjusting the screw within the sensor body.
NOTE: this sensor must be manually reset once tripped.
(See G.A. for location).
Operation Tests
1.
Switch on main power supply feeding unit. Turn
isolator switch on control panel to the ON
position, the mimic POWER ON indicator should
now be illuminated.
2.
Turn pump selector switch to the ON position for
one pump units or position 1 for two pump units.
Check that PUMP 1 mimic indicator is
illuminated. Repeat procedure for secondary
pump if fitted. If a three phase supply is being
used check pump is running in the correct
direction, if not reverse two phases at main
isolator. On two pump units turn selector switch
to PUMP 2 position and check PUMP 2 mimic
indicator is illuminated.
3.
Press the F key on the digital controller to enter
HAND condition. Press the raise key and check
valve is moving towards the open position,
press the lower key and check valve is moving
towards closed position. Press F key to return to
normal display.
4.
On twin pump units turn pump selector switch to
position 1. Trip circuit breaker 1 by pressing its
red test button, this should stop PUMP 1 and
start PUMP 2 automatically. Press green button
to reset circuit breaker.
5.
Simulate a high temperature alarm by providing
heat from the boiler and driving open the valve
to admit heat, or adjust high temperature sensor
to a lower setting. Once tripped the high
temperature alarm indicator should be
illuminated and the valve should motor to the
closed position. The unit will remain shut down
until the sensor is manually reset.
