Forced convection

FORCED 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.

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 regulations the KORAFLEX, KORALINE, KORAWALL model lines achieve optimal heating efficiency and considerable financial savings.

Regulation forms a central role in the heating and cooling outputs of trench heaters KORAFLEX with forced convection. Fans and thermoelectric actuators are supplied with 24 V DC, and fan rotations are as standard controlled by a voltage of 0–10 V DC.

EC fan system with disc-type synchronous motors in an aluminium chassis. It is characterised by very low power consumption and very quiet operation. The fan electronics ensure smooth operation at the required speed.
The FCR BOX electronic controller serves as a terminal block for connecting cables from the power supply, thermostat or BMS and the fans. It allows independent control of thermoelectric actuators for heating and cooling. KORAFLEX Amper FVA does not include the FCR BOX.
KORAFLEX Energy FVE and KORAFLEX Amper FVA trench heaters include a switched-mode power supply 230 V AC / 24 V DC and a terminal block for connection to the 230 V AC mains.

230 V AC / 24 V DC power supply according to the total power input of the trench heaters (not intended for KORAFLEX Amper FVA and KORAFLEX Energy FVE). Five types of power supplies are available for 60 W, 100 W, 150 W, 240 W and 480 W. The power supplies are supplied separately for installation in an electrical switchboard on a DIN rail.
Installation box for housing the DC power supply. Designed for 60 W, 100 W and 150 W power supplies.
Thermostats for 24 V DC: RDG 260T, RDG 260KN, HY607LIC.
24 V DC thermoelectric actuator, thermostatic valves, lockshield (not intended for KORAFLEX Amper FVA).

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, RDG 260T or HY607LIC thermostat function description

Trench heater output is controlled by fan speed and the flow of the heating/cooling medium through the exchanger. Control voltage is 24 V. SIEMENS RAB 21-DC, RDG 260T and HY607LIC thermostats operate the valve via a thermoelectric actuator and control fan speed with a 0–10 V DC signal. Speed can be set automatically or manually in three steps (rated at 7 V).

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.

KNX function (for BMS systems)
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 intended for humid environments, the stated description of the standard control system applies. The difference lies in placing the FCR BOX controller in a box with a higher degree of protection. The fan is fitted with stainless steel casing and its electronics are protected against splashing water. The convector is not designed for permanent flooding with pool water. Please familiarise yourself thoroughly with the warranty and operating conditions

KORAFLEX Energy (FVE)
It is powered by 230 V AC mains voltage. The switchedmode 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. Before commissioning, an initial inspection of the electrical installation must be carried out in accordance with the applicable national regulations and standards.
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.

KORAFLEX Amper (FVA)
The KORAFLEX Amper FVA electric convector is controlled by a control voltage of 0–10 V DC via a thermostat or a master BMS system. The control voltage determines the heater performance and the fan speed. The power supply of the heater is 230 V AC and is delivered via an IP 65 electrical box. The fans have a safe 24 V DC power supply. In the event of a fan failure, the electronics will shut off the power to the heating rod. In the event of an electronic failure, safety is ensured by a safety shut-off sensor. An additional control sensor makes sure that the temperature of the grille does not exceed the ambient temperature by more than 45 K. The grille is fixed to the convector with screws for safety reasons.

KORAWALL Optimal-V (WVO) and Pool-V (WVP)
Regulation elements are identical for all forced-convection products (OC systems). We recommend equipping the convector with the LM regulation valve with a higher flow rate.
