CFM/CFS CFR CFZ

Danfoss A/S 03/2001 DKCD VI.88.M2.22

088R0227

INSTRUCTIONS FOR INSTALLATION

The floor heating system consists of:

- Master controller CFM

- Slave controller CFS (if > 8 heating outputs)

- Room thermostats CFR

- Setback programmer CFZ (optional)

Master controller CFM

This controller governs the individual heat outputs via

wireless communication with the associated CFR.

Connection of 8 heating outputs is possible.

If more heating outputs are required, connect one or

max. two slave controllers CFS, each with connections

for 8 outputs. This allows max. 24 heating outputs to be

controlled.

The master/slave should be installed above the mani-

folds or near pump relay. Ensure easy access to plugs

and terminals. See instruction drawing on the opposite

page.

If two slave controllers are connected, move the jumper

in “slave 2” to position 2. See instruction drawing.

The connection cable for the CFS is 1 m (3.5 ft). Cable

lengths of up to 100 m can be used. Longer lengths

available from electrical suppliers.

Alarm

2 options available with respect to alarms given by the

CFM:

-Internal acoustic alarm can be selected by moving the

jumper marked “buzzer” from OFF to ON. See installa-

tion drawing.

-External alarm can be connected to the external alarm

relay marked %.

Technical data

Max. ambient temperature 140°F.

Voltage 24 AC, 60 Hz, 75 VA

Enclosure IP40

Room thermostat CFR

Before mounting the CFR(s), each must be assigned to

the CFM controller.

See the instructions that come with the room thermostat.

It is important to mark the CFR, e.g. with room or number,

to know where in the building it belongs. Labels are sup-

plied.

Zone regulator CFZ (Optional)

The setback programmer governs a maximum of 6 mas-

ter zones. For each zone an individual timing program

can be set. For reading and operating convenience, it is

recommended to place the CFZ at eye level.

The connection cable is 5 m (16 ft). Cable lengths up to

100 m (328 ft) are allowed. Additional lengths available

from electrical suppliers.

Putting into operation

LED for CFS 2

Fig.1

Fig. 2

Column and row LEDs show the

operating mode of the outputs.

Light: heat is “ON” to the room.

No light: heat is “OFF” to the

room

Example: When the LEDs of

the 4th column and the 1st

row are lit, heat is supplied to

output 4 of the CFM.

LED row for outputs

Assigning CFR to output(s)

-Connect the room thermostat (fig. 1) to the CFM, via the black

installation cable. The first vacant output in the registration

field will flash. Other vacant outputs will be lit, while outputs al-

ready registered will not be lit (fig. 2).

-If OK is pressed briefly, the room thermostat will be assigned

to the first available output causing the LED to go off (fig. 2).

If the CFR is to be assigned with more than one output, go to

these outputs by means of the +/- keys and confirm by press-

ing OK briefly.

When the installation cable is removed, the red LED under-

neath the battery cover (fig. 1) will flash for at least 3 minutes

(Thermostat in test mode).

Removal of assigned room thermostat

The CFR and the CFM must not be connected.

-Hold OK for 5 sec, the first LED in the row for assigned CFR(s)

will flash (fig. 2). Other LEDs for assigned CFR(s) will flash.

-Use the +/- keys to go to the CFR to be removed (it will flash).

-Confirm removal by pressing OK for 5 sec.. The LED light will

go off.

Test of CFR

If a defect in a CFR is suspected, the following test may be

carried out:

-Set the thermostat to the highest temperature.

-Move the function switch located on the right side of the

thermostat to a new position.

-If the LED underneath the battery cover (fig. 1) flashes quickly

within the first minute, the CFR is in order.

Transmission interval

A CFR transmits regularly. When a signal is received by the

CFM, two quick flashes are seen. Subsequently, the normal

operating mode will be displayed.

Operation

During normal operation, the status of the CFM outputs are

shown.

If the status of the outputs of the CFS is to be shown, scroll by

means of the +/- keys. After approx. 10 sec. the system reverts

to the output status of the CFM.

Troubleshooting

FCC ID: PGBTYPE-CFR , CAN 3934104209

This device complies with Part 15 of the FCC Rules and with

RSS-210 of Industry Canada and with RSS-210 of Industry

Canada:

Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received,

including interference that may cause undesired operation.

Warning: Changes or modifications to this unit not expressly

approved by the party responsible for compliance could void

the user’s authority to operate the equipment.

In the event pump zoning is used a

separate relay box, CPR, is needed

(Part 088HPRLY)

Max. 4 outputs per relay box. If 5-8

outputs are required then two relay

boxes are needed. Wire controller

outputs to relay box according to

typical wiring diagram. Electrical

specifications for zoning circulator

pump: Single phase, 115 V, 60 Hz,

and max. 3 A.

Normal operation during

test of room thermostat

· Reposition thermostat in room

until signal is clear.

· Reposition external antenna,

however if signal is still unclear

move external antenna to the

same floor as thermostat(s)

· Reposition room thermostat and

run test mode

· Mount external antenna if not

already installed.

· Eliminate interfering electronic

equipment

· Replace battery and test

thermostat

· Check heating supply to the

system and the circulator pump

· Check master control, CFM, is

properly wired.

· First check actuators for proper

wiring then replace fuse in

master/slave controller, 1.25A

· Check wire and connection

between master and slave

· Replace zone actuator

· Check heating supply to the

system and the circulator pump

· Replace battery, Lithium AA 3.6V
