FORCED CONVECTION

NATURAL CONVECTION – REGULATION and ACCESSORIES

Regulation of the heating or cooling medium flow forms a central role in the correct control of convector heating output. Correct selection of regulation elements guarantees a comfortable ambient temperature and contributes to heating cost minimalization. Fans and thermoelectric actuators are powered by 24 V DC and the fan speed is operated by 0-10V control voltage.

KORAFLEX FVO, FVE, FVP, F2V and F4V
KORALINE OLOC
KORAWALL WVO or WVP

Regulation is designed for all model lines with natural convection:
Outside temperature varies continuously during the heating period. Regulation elements are installed to the heating system to meet your desired ambient temperature and to eliminate the negative impact of outside temperature changes. Thanks to well designed regulation the KORAFLEX, KORALINE, KORAWALL model lines achieve optimal heating efficiency and considerable financial savings.

Optional accessories

A set of EC fans with synchronous motor in an aluminium frame.
Featuring very low power consumption and very quiet operation.
FCR-BOX electronic regulator which functions as a terminal block
or connecting the cable from the power supply, thermostat
or BMS and the fan. Ensures smooth operation of the fan at
required speed and independent control of thermoelectric actuators
for heating and cooling.
KORAFLEX Energy FVE models are fitted with switching
230 V AC / 24V DC power supply and a terminal block for connecting
230 V AC from the grille.

230 V AC / 24 V DC power supply according to the maximum
power consumption of the trench heater. Five types of power
supply units are available for 60 W, 100 W, 150 W, 240 W and
480 W. Power supply units are supplied separately for mounting
on the distribution board DIN rail assembly
Junction box. For mounting HDR-60, HDR-100 and HDR-150
power supply units.
SIEMENS 24 V DC RDG 160T or RDG 260KN thermostats
24 V DC Thermoelectric actuator, thermostatic valves, lockshield.
The NTC temperature sensor serves to block the fan until the
water in the heat exchanger has reached a sufficient level of heat
or coolness, thereby optimizing both functionality and power
consumption. It is delivered separately. For proper function it
must be placed on the heat exchanger.

Installation must be carried out in accordance with valid regulations and safety procedures! The manufacturer cannot be held liable for any defects, damages and injuries caused by improper installation.

RAB 21-DC or RDG 160T thermostat function description

Trench heater output is controlled by fan speed and the flow of heating / cooling medium through the exchanger. The control voltage is 24 V. The RAB 21 DC or RDG 160T Siemens thermostats control the heating medium valve with a thermoelectric actuator, and in addition control fan speed with a control voltage of 0–10V DC. Fan speed may be controlled automatically by the thermostat, or manually in three speed settings. Speed rating is set at a control signal size of 7 V. Fans start rotating when the temperature of the heating medium exceeds 37 °C. For cooling trench heaters it is recommended to use a second temperature sensor, actuated when the temperature drops below 15 °C. Temperature sensors are available as optional accessories.

Function description with BMS (Building Management System)

The BMS central control system may be used to control trench heaters. One BMS control output directly controls the opening / closing of valves and the other 0–10 V DC output controls fan speed. Rated heat output of trench heaters is achieved at 7 V DC. Valves and fans are supplied with 24 V DC.

Using the KNX system, trench heaters may be controlled with the RDG 260KN thermostat. The thermostat communicates with the KNX system, which transmits and receives data for the trench heater.

Information on individual model lines

KORAFLEX Pool-V FVP

For KORAFLEX Pool-V humid environment trench heaters, the standard control system description applies. The difference lies in placing the FCR-BOX in a pattress box with a higher degree of protection. The fan is equipped with stainless steel casing and its electronics are protected against splashing water. For this model we recommend using a temperature sensor that monitors the temperature in the pool area. The sensor is designed for RDG 160T thermostats. The trench heater is not designed to be permanently flooded with pool water. Please familiarise yourself thoroughly with the warranty conditions and conditions of use.

KORAFLEX Energy FVE

It is powered by 230V AC mains voltage. The switched-mode power supply is situated inside the convector and converts mains voltage to 24 V DC. Fan speed is controlled by 0–10 V DC controlled voltage either from the BMS or the thermostat. Electrical installation design must be carried out by a suitably qualified person and must comply with relevant regulations. Installation and maintenance of the electrical installation must be carried out by a qualified electrical technician. Prior to commissioning, an inspection and testing of the electrical installation must be carried out in accordance with ČSN 33 1500. KORAFLEX Energy FVE convectors are powered with 230V alternating current mains electricity. Therefore the electric branch must be equipped with a residual current device with a tripping current of 30 mA. These trench heaters are to be used solely in dry environments, and only for heating.

KORAWALL Optimal-V (WVO) and Pool-V (WVP)

Regulation elements are identical for all forced-convection products (OC system). We recommend equipping the convector with the LM regulation valve with a higher flow rate.
