PARAMOUNT
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.
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.
Table 2 – Check List for Start Up and Faults
Problem Cause Remedy
Heating system does
not start up
- Main switch for mains power not
switched on
◊ Switch on
- Operating switch (3) on control panel
on PARAMOUNT switched off
◊ Switch on
- No heat requirement present
◊ On systems with outdoor sensor:
it is too warm outdoors for heating (heating
curve)
◊ Hot water circuit not activated
- Wrong day/time on RRG/EMS
(e.g. daylight savings time)
◊ Correct day and time (see instructions for
RRG/EMS).
- Wrong operating mode set on room
control module.
◊ Check operating mode (AUTO Manual or
Ready).
- Gas shut-off device CLOSED
◊ Open gas cock
- Gas connection pressure too low.
y Check gas connection pressure
- External mains fuse tripped
- Fuse FI in BMU control module
defective
y Check mains fuse for the boiler.
y Replace fuse F1
Insufficient Heat
- For operation
without outdoor
temperature
Boiler temperatures heats up only to
approx. 55°C
◊ Always operate PARAMOUNT boiler with
outdoor temperature sensor!
- For operation with
outdoor
temperature sensor
PARAMOUNT in night set-back mode
◊ 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.
Heating curve not “matched” to personal
requirements.
◊ Adjust steepness of heating curve as
required
No heating program
from RTW or EMS
Jumper at X6, terminal N5 and P2 not
removed
y Remove jumper, see wiring diagram (only
RAV/RTW/RTD or EMS/DSU)
Hot water not heated
sufficiently
Hot water temperature set too low.
◊ Check hot water temperature on heating
circuit module HKM or on RRG and set
higher if required.
Resistor R3 not removed at X6, B3
y When a hot water tank is connected,
resistor R3 must be removed!
Flashing numbers
on controller BMU
Various causes depending on error
message
y Observe error message in Error message
table (Table 11, p. 34)
No problems with
operation of
PARAMOUNT boiler
Perform maintenance/cleaning once a
year
◊ We recommend concluding a service
contract with Potterton Commercial.
y This work should always be left to a heating engineer.
