Kima ZONE 50, ZONE 30 Installation Manual

ZONE 50 is an electronic thermostat for electric underoor heating system with external oor
sensor.
ZONE 50 can be installed in standard wall box or ush mounted on the wall with an external
frame box.
ZONE 50 controls and regulate the oor temperature to achieve the best room comfort.
ZONE 50 is using the adaptive PWM- and PI-technics to to give the best performance and to
extend ZONE 50s lifetime.
ZONE 50 should not be used to eliminate over temperatures in the oor construction.
The only way to eliminate overtemperatures is to design the oor construction with the right
W/m2 and compensate for the oor constructions thermal insulation and the Wattage per
linear meter Warm Floor Heating Cable or Wattage per square meter Warm Floor Mat.
If the buildings insulation properties is poor it can be compensated with another external
heat source. If ventilation/heat pump/air-condition are chosen as the external heat source
it is important that the temperature setting for this heat sources will not be lower than the
oor temperature, this will save energy.
The under oor heating construction should never be exposed to high temperatures to elimi­nate the risk of re. The worst situation will be when the construction have a high power
output per sqm oor and the oor construction is thin with a good thermal insulation and
the oor surface will be covered with a carpet or any other good thermal insulating material.
The maximum allowed temperatures is depending on the surrounding material and regulated
by the electrical standards, regulations and directives.

- Maximum temperature in a oor construction according to electrical standards is 80˚C.

- The general maximum temperature for combustible material is 80˚C.

- Maximum operating temperature for Heating Cable or Heating Mat see the products
technical specications.

- The maximum temperature for water membrane are quite low (50˚C), see the
producers technical specications.
ZONE 50 complies with the directives for electrical safety and EMC compatibility.
ZONE 50 are CE-marked and complies with the following standards:

- EN 61000-6-2, EN 61000-6-3 EN 60730-1 and 60320-2-9.
ZONE 50 should only be used when the whole installation complies with electrical standards,
regulations, directives and KIMAs installation manuals.

ZONE 50 should only be installed by authorized installers.

If ZONE 50 have been exposed to violence or got damaged, it should be carefully controlled
by qualied personnel before it will be connected to the mains.

Installation oor sensor

It makes it easier if the oor sensor is installed in an end sealed electric conduit pipe, if it
needs to be replaced.
The oor sensor should be installed in an open oor area between two heating cables about
0,5 m from the wall. It is important that the sensor will not be placed in an area were the
heat can be thermally blocked with xed or movable furniture, wardrobes, kitchen cupboards,
etc.
If needed the oor sensor cable can be extended with a separate ordinary 1,5 mm2 instal­lation cable (maximum length see technical specications). The oor sensor should not be
installed in the same electrical conduit pipe as the heatingcables/heatingmats cold tail or
any other electrical cables. If the oor sensor is connected to a cable with metallic sheath.
Don´t earth the metallic sheath.

Economy function, Day or Night setback
Lowering the oor temperature with a preset value, see Technical specications, with an ex­ternal signal. This function doesn’t need to be used if not needed. The external timer should
be installed on a suitable place for example at the switchboard or a manual switch that could
be installed next to ZONE 50. The timer or switch can control more than one thermostat at
the same time. Important to use the right control signal, see technical specications.
LED light will be green when the economy signal is active and red when the heatingcable/
heatingmat is energized. (see Fig. 1)

Frost protection

Frost protection will maintain the oor/room temperature at a low temperature, see techni­cal specications. This function doesn’t need to be used if not needed. The external timer
should be installed on a suitable place for example at the switchboard or a manual switch
that could be installed next to ZONE 50.
The timer or switch can control more than one thermostat at the same time. Important
to use the right control signal (the signal should be connected via a rectier diode), see
technical specications. (See Fig. 2)

Installing ZONE 50

1. Open the plastic front cover and unscrew the screw. The thermostat should not be
opened in any other way.

2. Connecting cables (see g.)
Terminal 1: Live (L)
Terminal 2: Neutral (N)
Terminal 3-4: Heaingcable/Heatingmat (Maximum Load 3600W/16Amp)
Terminal 5-6: Floor sensor
Terminal S: Control signal from external timer or switch to operate Economy function,
Day or Night setback or Frost protection if decided to use.
PS. Before the Heating Cable or Heating Mat is connected to ZONE 50 the resistance
and insulation properties should be checked. See Heating Cable or Heating Mat
installation manual.

3. Install ZONE 50 with the frame against the wall or over a wall box and x it with screws.
Fit the covers.

4. Don’t turn the heating on to early, before concrete or liquid concrete have cured
enough. See manufactures specications.

5. LED light will be red when the Heating Cable/Heating Mat is energized. Depending
on the thickness of the oor construction and how low surrounding temperature are, it
will take longer time to achieve set temperatures. If the heat losses are high, it could
be a problem to achieve set temperatures.
If their will be no heat, see fault nding list.

Documentation

Installations manual, Users manuals and any other documents for the oor construction
should be led near by the switchboard together with Warranty documents that can prove
that it has been an authorized installer that are responsible for the installation.

Environmental disposal

ZONE 50 is an electronic product and should therefor be returned to any envi­ronmental approved depo stations.
Products marked with this symbol can’t be disposed together with the normal
household waste. It should be delivered to a waste collection centre in
accordance with the local regulations.

Faultnding ZONE 50

Fault tracing should be done by KIMA authorized fault nder.

The oor will not be warm
A. Check that the cables have been connected in the right way and the terminal screws
are tight.
B. Check the voltage on terminal 1 and 2.
C. Check that the switch on ZONE 50 is switched on. Check the voltage on terminal 3 and
4 when the Heating Cable/Heating Mat is on and the LED light is lit as said in
paragraph 5. Measure the electric current with a clamp meter and compare it with the
technical specications for the Heating Cable/Heating Mat
D. Disconnect the Heating Cable/Heating Mat and check the total resistance and the
insulation properties and compare them with the recorded values from the installation
that should be led near the switchboard and compare it with the technical
specications.
E. If the measured electrical values are correct according to the technical specications
and the construction doesn’t get warm enough the problem could be that the heat
losses are greater than the input power and the reasons could be cold spots. (PS. Do
not increase the power out put, that will instead increase the risk of re and also
shorten the ageing properties of the Heating Cable/Heating Mat) Analyze the total
building constructions insulation properties and try to nd any cold spot that can
cause the problem. If the oor construction is a concrete slab on the ground check
the moisture, that could be a great problem due to better heat conductivity. Another
problem could be that their is a could area under the oor construction and that’s why
it important to insulate the construction well.
F. Disconnect the oor sensor on terminal 5-6 and there will be an error code in the LCD
display ”E1”, the LED light will ash red once. The same will happened if terminal 5-6
are shortened.
G. Check the oor sensors resistance and compare it with the technical specications.
The reading should only change with the temperature.
H. If ZONE 50 are turned on and the surrounding temperature are lower than -20˚C,
ZONE 50 will turn the relay off and when the temperature increase over -20˚C it
will turn on again.
I. If the temperature in the thermostat will be greater than 70˚C it will turn the relay of
for 10 minutes so the temperature will decrease and the LED light will ash red ve
times and a error code ”E5” will be presented in the LCD display.
J. Contact the distributor ZONE 50 has been purchased from.

The oor is energized all the time

a. Check that the cables have been connected in the right way and the terminal screws
are tight.
b. Disconnect the oor sensor on terminal 5-6 and there will be an error code in the LCD
display ”E1”, the LED light will ash red once. The same will happened if terminal 5-6
are shortened.
c. Check the oor sensors resistance and compare it with the technical specications.
The reading should only change with the temperature.
d. Contact the distributor ZONE 50 has been purchased from.

Sensor resistance at diffrent temperatures

Users manual

ZONE 50 with a oor sensor are the best and an easy way to control and regulate the
underoor heating system and to achieve the best comfort. Underoor Heating system are
always slow reacting system and that depends on the thickness of the oor construction.
Thicker cement based oor constructions gives also a possibility to accumulate heat.
If the building have poor insulation value and the heat losses are considerable is it pos­sible to lower the energy consumption by using the Economy function with an external
switch or external timer, see technical specications.
ZONE 50 factory set value are 5,0 LCD-display = 25,0˚C oor temperature.
ZONE 50 LCD-display controls between 0-10. To change setting press blue or red button
and the LCD-display will change 0,1 up or down. It is possible to change the LCD-display
to degree C operating mode, see Programming.
With ZONE 50 their is also the possibility to change the temperature reading in the
LCD-display (Offset) compared with the actual oor temperature to match measured room
temperature, maximum offset 8˚C up or down. This will only work when ZONE 50 is opera­ting in the degree C mode.
ZONE 50 is maintenance free.
