1. Operating instructions for the user and the professional

RTI-E3

The RTI-E3 is an electronic 2-point control unit; i.e. the blower of the storage heater is switched on by the RTI-E3, operated at a constant speed, and then switched off again.

RTI-EP2

The RTI-EP2 is an electronic proportional control unit; i.e. the speed of the storage heater blower motor is steplessly adjusted by the RTI-EP2 to suit the heat requirement.

In this situation, the speed regulation of the blower motor is effected as a function of the difference between the room temperature (the actual temperature) and the temperature which has been set at the selector button R2 (the reference temperature). The smaller this difference, the lower the speed of the blower motor.

However, if the storage heater is being operated with a supplementary heating system, then the RTI-EP2 automatically switches over to a 2-point control arrangement; i.e. if heat is being given off, then the blower motors only run at full capacity. If the supplementary heating is switched off by means of the switch on the operating panel, then the RTI-EP2 again operates as a proportional control unit.

1.1 Mode of operation

The discharge control unit is switched on and off by means of the S2 switch on the control panel of the storage heater (ON = "0").

The room temperature desired can be steplessly adjusted between about 5 to 35 °C by means of the R2 selector button on the operating panel. If the selector button is in the central position, the room temperature will be kept to a constant temperature of about 20 °C. If the room temperature drops below the preset value, the discharge control unit automatically switches on the storage heater blower motors, so that the stored heat is blown into the room.

After adjusting the temperature it may last y few minutes before the blower will start due to technical reasons.

On very cold days, it is recommended that the discharge control unit be switched on if no-one is going to be present for several days, in order to keep the room temperature at about 10 °C, for example, so as to prevent the building or the room from becoming too cold (to protect against freezing).

Night-time heating reduction

By utilising an external switch or timeclock, a temperature reduction of approx. 4 K can be achieved.

2. Installation instructions for the professional

The discharge control unit must be installed by an approved qualified installer, following these Operating and Installation Instructions as well as the instructions for the storage heater.

All electrical connection and installation work is to be carried out in accordance with VDE 0100 provisions, the regulations of the electricity supply utility companies concerned, and the corresponding national and regional regulations.

When connecting the storage heater to an automatic charging control device, it is possible, even with the fuses removed, that voltage will still be present at the terminals A1/Z1 - A2/Z2.

If several storage heaters are being set up next to one another, care is to be taken to ensure that the discharge control unit is installed in the right-hand outer device. This guarantees that the room temperature can be detected without any problem.

2.2.1 Installation sequence

→ Remove the air outlet and inlet grilles, the front wall, and the right side wall, as described in the installation instructions for the storage heater.
→ Push the blind cap for the switch (20) and temperature selector button (21) out of the operating panel from the switchbox side, using a mechanical aid.
⇒ Push the ON/OFF switch (S2) with the „flat plug upwards" into the operating panel from the front.

2.1 Packing unit

1 discharge control unit with
- connection lead for charge and discharge control unit
- 6-pin plug connector with cable harness
1 ON/OFF switch
1 adjuster (potentiometer) with connection lead
1 temperature selector button
1 set of operating and installation instructions
1 room temperature sensor with 2 screws
2 separate switch leads for switches

2.2 Installation

Before starting installation work, isolate the storage heater from the electricity supply.

graph LR
    A["20"] --> B["STEEL-TRON"]
    B --> C["S2"]
    C --> D["R2"]
    D --> E["8723.0"]

⇒ Push the temperature selector button (R2) into the operating panel and turn it as far as the left-hand stop.
Rotate the shaft of the potentiometer as far as the left-hand stop.

Engage the potentiometer into the operating panel from the switchbox side (check that the potentiometer shaft is properly located).

Lay the 3-pole connection lead of the potentiometer along behind the angle plate to the plug-in location of the discharge control unit (in this situation, fix the connection lead to the operating panel and the angle plate by means of the cable holder).

Pivot the angle plate located in the switchbox forwards in order to accommodate the mains connection terminals, after releasing (not unscrewing) the screw located in the rear wall.
⇒ Plug the connection lead (X25) on the discharge control unit (A2) onto the charge control unit (A1).

→ Guide the 6-pin plug connector of the discharge control unit along behind the angle plate and upwards, insert it form above into the plug-in locations „TA“ to „N“ of the connection terminal X2, and screw it tight (push the cable harness into the cable holder provided).
→ Plug the discharge control unit into the longitudinal holes located above the charge control unit and engage it in position.
⇒ Screw the room temperature sensor (B2) with two screws (2.9 x 6.5) to the front inclined edge of the baseplate. Plug the connection cable into the plug-in location X20 of the discharge control unit.
⇒ Plug the connection lead of the potentiometer into the plug-in location X21 of the discharge control unit.
→ Guide the separate leads provided along behind the angle plate and connect them as shown in the following table (to the terminals X1 and X2 from below):

Designation	Laying
	from
Lead (black)	L (X1)	S2 (top plug-in location)
Lead (brown)	LE'(X2)	S2 (bottom plug-in location)

The leads must not come in contact with the operating panel conductor plate or simply insulated leads for safety extra-low voltage (SELV). Incorporate the leads to the S2 switch into the existing cable harness (drillers can be opened and then closed again).

⇒ Pivot the angle plate back to the rear again and screw it tight.
⇒ Secure the side wall, front wall, and air outlet and inlet grilles to the appliance once again (respect the installation sequence).

The toothed disks must be inserted beneath the securing screws of the side wall and the front wall (protective conductor connection).

2.2.3 Night time heating reduction - connection of an external time-clock

After installation, a switch or timeclock should be wired to terminals L and TA on terminal block X2. A temperature reduction of approximately 4 K can then be achieved.

The wiring for this modification must be provided by the installer; they are not included in the kit.

2.3 Function test

Set the ON/OFF switch to the position "0". Now rotate the temperature selector button until the blower of the storage heater switches on. If the blower does not switch on, the operating and fault displays on the charge and discharge control units are to be observed.
