LG Electronics RVL469 Mechanical design, Fault messages and flow temperature alarm, elements

Communication	To provide this function, connection of the RVL469 to ist partner unit via the data bus is
	mandatory. Each RVL469 requires one partner unit.
	Communication with other units also takes place via the data bus and facilitates:
	– Signalling of heat demand to the heat source
	– Exchange of locking and enforced signals
	– Exchange of measured values such as outside temperature, return temperature, flow
	temperature and of clock signals
	– Communication with other devices
	– Reception of heat demand signals from the SYNERGYR OZW30 central unit (from
	software version 3.0)
	– Exchange of error messages

Fault messages and flow temperature alarm

–Fault message in the event of sensor faults

–Fault message in the event of data bus faults

–Flow temperature alarm; adjustable is a period of time during which the flow temp- perature may stay outside the set limits; a fault message is given when the time has elapsed

Other functions	– Display of parameters, actual values, operational statuses and fault messages
	– Simulation of outside temperature
	– Relay test; all relays can be controlled manually
	– Sensor test; all measured values of the sensors can be displayed
	– Testing the contacts connected to terminals H1–M and H2–M
	– Outside temperature-dependent frost protection for the plant; a minimum flow tem-
	perature is maintained, its setpoint and the response threshold can be adjusted
	– Pump overrun time to prevent buildup of heat
	– Periodic pump run (pump kick) to prevent seizing of the pump in the summer
	– Controller hours run meter

Mechanical design
	The RVL469 is comprised of controller insert, which accommodates the electronics, the
	power section, the output relays and - on the front - all operating elements, and the
	base, which carries the connection terminals. The operating elements are located be-
	hind a lockable transparent cover.
	The operating instructions can be inserted in the transparent cover.
	The controller insert is secured to the base with two screws, one of which can be
	sealed. The cover can also be sealed.
	The RVL469 can be fitted in three different ways:
	– Wall mounting (on a wall, in the control panel, etc.)
	– Rail mounting (on a standard DIN mounting rail)
	– Flush panel mounting (control panel door, etc.)
Analog operating	– Buttons for selecting the required operating mode
elements	– Info button
	– Direct adjustment of the heating curve with the the little bar on the front of the unit
	(only if analog setting is selected)
	– Knob for manual readjustment of the room temperature
	– Three buttons for manual operation and manual positioning commands
Digital operating	The entry or readjustment of all setting parameters, activation of optional functions and
elements	reading of actual values and statuses is made according to the operating line principle.
	An operating line with an associated number is assigned to each parameter, each actual
	value and each function that can be selected.
	One pair of buttons is used to select an operating line and one pair to readjust the dis-
	play.
