RECEIPT Please check delivery immediately on receipt for accuracy and damage. If damaged, please notify carrier and your supplier immediately. In case of delayed notification, any possible claim may be void. STORAGE The place of storage must be waterproof, vibration-free and free of temperature variations. Damage due to improper transportation, storage or delay in putting into operation are not liable for warranty. OPERATION / USE With the ZMEA module it is possible to operate all units KWL 250.. (with exception of the kitchen unit), KWLC 350 and KWLC 650 beginning with version 001 with external control signals. Additionally 3 operating conditions can be monitored via the volt free terminals. ATTENTION: The external triggering with the ZMEA overrides the normal controller. The normal controller (with or without a clock KWL-WSU) cannot be operated at the same time as the external triggering with the ZMEA (switch S1 selects either the ZMEA or the normal controller). Control signals (input): The control signals can be acheived with volt free relays. The switching occurs with a voltage of 24 V DC. Terminal 1-2: must be linked! Terminal 4-5: activates medium speed*. Terminal 4-6: activates full speed *. * Speed switching logic see ZMEA wiring diagram! Terminal 4-7: heater enabled (heater ON, depending on desired value setting at the potentiometer in the KWL-unit) Terminal 9-8: To lower or raise required temperature in the KWL-unit dial +- 15°C at the potentiometer T1. Terminal 9-10: To lower or raise required temperature in the KWL-unit dial +- 15°C at the potentiometer T 2. Hereby can be worked with 3 desired values: Terminal 8 and 10 not activated = desired value 1 Terminal 8 activated = desired value 2 Terminal 10 activated = desired value 3 Status of ZMEA: LED on = ZMEA ready Status of unit (outputs): Terminal 11-12, contact closed = ZMPA on standby Terminal 13-14, contact closed = alarm, overheat thermostat with contacts, manual reset required. Terminal 15-16, contact closed = alarm, filter dirty using duct sensor (DDS sensor optional) Potentiometer T1/T2: Displacement of required temperature, see terminal 9-8 and 9-10 at ZMEA. Switch S1: Switch to choose ZPEA or supplied controller. Switch not pressed = mode ZMEA Another use is not possible CONNECTION All work may only be carried out by a qualified person. All relevant national and international safety and installation regulations are to be adhered to ATTENTION: Electrical connection may only be carried out with the equipment fully isolated from the supply. The cable entry happens via cable gland (M20 x 1,5). A control input cable LiCY with .. x 0,25 mm² can be used for the control inputs (24V DC). The outputs are laid out according to assigned switching voltage (max.230V~). A cable with 8 x 0,25 mm² is required for the data cable. INSTALLATION Flush mounted installation on an even surface. • Unscrew front cover. • Fix in place lower part of casing. • Insert electric connecting cables through cable gland. Strip and wire to terminal block in accordance with the wiring diagram. • Test for leaks. • Screw on front cover. • Check operation. TECHNICAL DATA Supply voltage: external from KWL Relay outputs: AC1/6A/250V~ Dimensions L x W x D: 110 x 110 x 65 mm (without cable gland) Protection to: IP 54 Max. ambient temperature: 0 ° to +60 °C Protection class: II ACCESSORIES AND SWITCHES The use of accessories not offered or recommended by Helios is not permitted. Any resulting damage is not liable for warranty. WARRANTY - EXCLUSION OF LIABLITY If the preceding instructions are not observed all warranty claims are invalid. This also applies to any liability claims extended to the manufacturer. CERTIFICATES If the product is installed correctly and used to its intended purpose, it confirms to all applicable European Standards at its date of manufacture.
