START-UP AND CHECK LIST
Start Up: Before commissioning the boiler read the
operating instructions and observe the "check list" in
the table below!
Initial operation should be accomplished by a heating
engineer who advised the user regarding handling
and operation of the unit and its safety equipment
and submits to the operator the operating instructions
for the heating system.
Table 2 – Check List for Start Up and Faults
Problem
Heating system does
not start up
Insufficient Heat
- For operation
without outdoor
temperature
- For operation with
outdoor
temperature sensor
No heating program
from RTW or EMS
Hot water not heated
sufficiently
Flashing numbers
on controller BMU
No problems with
operation of
PARAMOUNT boiler
y This work should always be left to a heating engineer.
CONTROL PANEL
POTTERTON COMMERCIAL PRODUCTS DIVISION
INSTALLATION , OPERATION AND MAINTENANCE MANUAL
Cause
- Main switch for mains power not
switched on
- Operating switch (3) on control panel
on PARAMOUNT switched off
- No heat requirement present
- Wrong day/time on RRG/EMS
(e.g. daylight savings time)
- Wrong operating mode set on room
control module.
- Gas shut-off device CLOSED
- Gas connection pressure too low.
- External mains fuse tripped
- Fuse FI in BMU control module
defective
Boiler temperatures heats up only to
approx. 55°C
PARAMOUNT in night set-back mode
Heating curve not "matched" to personal
requirements.
Jumper at X6, terminal N5 and P2 not
removed
Hot water temperature set too low.
Resistor R3 not removed at X6, B3
Various causes depending on error
message
Perform maintenance/cleaning once a
year
Important Notes: These instructions should always
be kept in the boiler room where they are readily
available.
For optimum fault free operation:
- set hydraulic system correctly (parameter 552)
- refer to wiring diagram (page 8)
- set the suitable heating curve, room control
RRG is used or a HKM with a room thermostat.
◊ Switch on
◊ Switch on
◊ On systems with outdoor sensor:
it is too warm outdoors for heating (heating
curve)
◊ Hot water circuit not activated
◊ Correct day and time (see instructions for
RRG/EMS).
◊ Check operating mode (AUTO Manual or
Ready).
◊ Open gas cock
y Check gas connection pressure
y Check mains fuse for the boiler.
y Replace fuse F1
◊ Always operate PARAMOUNT boiler with
outdoor temperature sensor!
◊ Check the heating program
◊ Have you pressed the Presence button
(RRG only)
◊ Set room temperature knob on RRG or
parameter "P 1" on Control Module higher.
◊ Adjust steepness of heating curve as
required
y Remove jumper, see wiring diagram (only
RAV/RTW/RTD or EMS/DSU)
◊ Check hot water temperature on heating
circuit module HKM or on RRG and set
higher if required.
y When a hot water tank is connected,
resistor R3 must be removed!
y Observe error message in Error message
table (Table 11, p. 34)
◊ We recommend concluding a service
contract with Potterton Commercial.
