The CER boilers are suitable for radiators, under-floor heating, added solar heat and domestic hot

water

Consult ATLANTIC BOILERS for suitable circuit arrangements.

1.1 METHOD OF OPERATION

The CER boiler is designed for closed-circuit heating

in both domestic and commercial installations.

Four immersion heaters are positioned within a

cast aluminium-silicium heat exchanger.

Turbulent water flow within the exchanger gives

an optimum rate of heat transfer. With this high heat transfer,

the immersion heaters comfortably work with longer

life at lower temperatures. Another advantage comes

from the modulating output. Conventional electrical

heating switches ON/OFF throughout operation.

Modulating heating means agentle,

varying load on the immersion heaters.

Heating flow and return pipes are positioned

atthe base of the boiler.

2. Digital controller

3. Power output to pumps & control valve

4. Power input to the boiler

5. Terminals to PT1000 external sensors

6. Stop and limit control terminals

7. Mechanical safety valve

8. Automatic air vent

9. On/offmanual control panel

1.2 IMMERSION HEATERS

Each heater is shaped in a helicoil which

assists the heat transfer.There are four

heaters in the boiler - each powered at 2kW or 3kW

They are screwed down into the four

Tubular shapes of each heat exchanger

Single and three phase cable terminals are behind

and on top of the Boiler Control Panel

The fascia panel has to be removed to enable the cable,

to be laid neatly and secured

A is where the external cables enter

1.5 FIXING THE CER BOILER TO THE WALL

1. Remove allen screws A & B from the underside of the casing

2. Lay the boiler body on its back, remove the fascia panel and note

the positions of the wall lugs

3. Fix minimum diameter 8mm screws to the wall.

4. Hang the boiler body from the screws; adjust as necessary.

1.6 HYDRAULIC CONNECTIONS

The CER boiler has 32mm flow (A) and return (B) connections

from the underside.

The flow must be fitted with a safety valve, a shunt pump

A dial thermometer & pressure gauge and an

isolating ball valve. The return, leading into the boiler,

must have an isolating ball valve, a strainer and

a cold feed an expansion connection,

Including the expansion vessel.

1.4 BOILER DIMENSIONS

1.7 PRECAUTIONS

Fix the boiler firmly to a solid wall

Leave approximately 500mm clearance around the boiler

All electrical wiring must be installed by a qualified electrician

The boiler must receive its power supply through an isolator and a circuit breaker

The power supply cable cross-section must be sized according to the boiler power

The power supply isolator mustbe positioned close to the boiler for safe maintenance work

Live neutral and earth cables must be traced and labelled

The boiler must never be switched on when without casing and fixing screws

Never adjust terminal fixings when boiler alive

Do not operate in manual mode without a competent engineer being present

PUMP AND CONTROL VALVE TERMINALS (On lower left hand side of the boiler)

Heating pump P1 (single phase) is connected to (A) – L N E

Heating pump P2 (single phase) is connected to (B) – L N E

High limit – see red arrow position marked “STOP”

This has a link placed at the Factory over-riding “STOP”

Connect to a high limit thermostat located in the

flow pipe for any critical system

Any high temperature sensitive space heating system

and remove the link

POWER OUTPUT

DIGITAL CONTROLLER

Switch 1. OFF

–

Limit of 50% power output

ON – Power output sufficient for frost protection

Switch 2. OFF – 50% boiler output if (A) is open

ON – Boiler output if (A) is closed

Switch 3. OFF – Single phase supply

ON – Three phase supply

Power output limit contact

- Bridged at the factory

- Remove bridge to limit power output to 50%

- Remove bridge to satisfy low price tariff

- Remove bridge to avoid peak period penalty

2.2 DIGITAL CONTROLLER (on lower right-hand side of boiler)

(1) Top card, on controller, provides Opentherm sensor control

(2) Lower card provides 20 indicators

(3) 5 adjustable clock codes

(4) Programme Set at factory

(5) Multi-socket Installed at factory

(6) Power limit system (see digital controller settings A & C)

USE OF THE SETPOINTS AND CLOCK CODES

(A) Selection of chosen heating circuit

(B) Slope of weather curve

For underfloor heating setting is 0

(D) Zone 1 setting for heating type

(E) Zone 2 setting for 2nd heating type

(F) Table of boiler power outputs

(G) Table of zone temperatures

2.4 CALIBRATION TO CLOCK CODE A (CONFIG)

0,3, 5, 6, 7 not used

1 one zone underfloor heating (with option DHW)

2 one zone radiators (with option DHW)

4 two zones; one with radiators; one underfloor (with option DHW)

8 manual setting to dry out the boiler & space are dry

9 automatic setting to dry out the boiler & space are dry

SLOPEOF THE WEATHER CURVE – CLOCK CODEB

The Slope Facility (0 to 9) is available (9) for a radiator circuit, (0) for underfloor.

The position (0) lowers flow temperature against outside weather

The position (9) gives maximum flow temperature againstoutside weather

VARIATION IN ELECTRICAL POWER –CLOCK CODE C

Power variation is a percentage of the nominal output – see Table (F).

For example – for a 50% reduction of the power, adjust to setting 4

ZONE SETTINGS – CLOCK CODES (D) and (E)

The two zone flow temperatures can be separately adjusted

The temperature is selected at table G

For example: 2 circuits : 1 radiators and 1 underfloor heating

For zone 1 at 70°C; set clock code D at 7

For zone 2 at 50°C; set clock code E at 3

PLEASE NOTE that OT1 is reserved to the circuit with high temperature, also radiators

PLEASE NOTE that OT2 is reserved to underfloor heating, except for 2 radiator circuits

Switch assembly 1 to 10

To restrict the boiler heat output, switch off H4, H3, and H2 with all switches off,minimal heat

outputwill remain for frost protection.

Switch assembly V1+ V1- V2-, 01, 02 to fix the position of the 3 valves

2.7 ELECTRONIC RELAYS

2.8 DRYING OUT THE NEW BUILDING

Modest flow temperature should be used.

Set clock code on 9 to give automatically

48 hours at 25°C,

then 48 hours at 30°C, then 96 hours at 35°C

then 48 hours at 30°C, then 48 hours 25°C

then 48 hours at 20°C – see graph below

Electronic relays operate each pump, each 3-way mixing

valve and each 2-position valve.

Each valve has 2 power and 2 control contacts.

See the output power control panel has one relay

See the digital controller has one terminal marked P1 for

pump 1 and one terminal also marked P2 for pump2 see

See the 3-way valve require two terminals marked V1

for zone 1 and terminals marked V2 for zone 2
