SCALE
ANALOGUE OUTPUTS ⁄
CAPACITY LIMIT
Each of the three analogue outputs (
Y1
/
Y2
/
Y3
) can be assigned a minimum and maximum output voltage
(between 0...100 %) (default: min = 0 % / max = 100 %).
The capacity specification from the control circuit (0...100 %) is then scaled through the
minimum output voltage to the maximum one.
Example:
To have the EC fan always work at the maximum speed, set the minimum output voltage to 10 % (1 V)
and the maximum output voltage to 70 % (7 V).
In that case, the 0...100 % control circuit output (Control Loop) on the analogue output is scaled to 10...70 % .
This helps to minimise blower noise and fan speed.
The values are available in connected systems for the bus master to write/read.

The unit types
RYM
ASKON
®
620
/
630
/
650
/
660
each have three relay outputs (
RLY1
/
2
/
3
)
to be used for controlling three-speed blowers (one relay switches with time).
Relay 1
“ON”: at approx.
30 %
of blower consumption
Relay 2
“ON”: at approx.
60 %
of blower consumption
Relay 3
“ON”: at approx.
90 %
of blower consumption
The relays switch to
“OFF” if the consumption is approx. 20
% below the respective switch-on value.
NOTE:
To use the relay outputs to control the fans, the
operating mode
of the analogue output
Y1
must be set to “Fan” (default).
NOTE: Types 620
/
650
have been designed for a maximum nominal resistive load of 0.5 A.
Types 630
/
660
have been designed for a maximum nominal resistive load of 7 A.

OPEN ⁄ CLOSE
Typ 650
(0.5 A)
The
RYM
ASKON
®
650
unit type has a fourth 230
V AC relay (
RLY4
)
to interconnect heating and cooling valves using 230
V AC “OPEN/CLOSE”.
Ensure to set output
Y2
to one of the following configurations
(see chapter “Analogue outputs modes”):
•
Htg Stage1 Stat
If the
Y2
output capacity exceeds 10
%,
RLY4
switches heating stage 1.
If the
Y2
output capacity is 0
%,
RLY4
switches heating stage 1 back.
•
Clg Stage1 Stat
If the
Y2
output capacity exceeds 10
%,
RLY4
switches cooling stage 1.
If the
Y2
output capacity is 0
%,
RLY4
switches cooling stage 1 back.
• Fan Stat
If the
Y2
output capacity exceeds 10
%,
RLY4
switches the fan.
If the
Y2
output capacity is 0
%,
RLY4
switches the fan back.
Type 650
also allows
Y1
to be configured for “Htg Stage1 Stat” or “Clg Stage1 Stat”.
In that case, relay 3 (
RLY3
) switches another open/close valve according to the description above.
This allows the controller to be used for heating and for cooling control of open/close valves.
If this application requires an additional fan control, use an
EC fan
.
It will be activated by the
Y3
analogue output (0...10
V, EC fan).
Ensure to configure the
Y3
output to “Fan” (see chapter “Analogue output modes”).
NOTE: Type 650
has been designed for a maximum nominal resistive load of 0.5 A.
