BUILDING AUTOMATION

Parameter “PWM cycle time for continuous[60..65535]s”

This parameter setting the PWM cycle time for continuous. Options:

60..65535

Note: To extend the service life of the relay and the controlled equipment, the pulse period is set as long as possible.

Under the 1bit control type, pulse width control (PWM) is only used to control the actions of thermostat fault, forced operation mode, and bus voltage re-

covery.

Parameter “Control telegram is received as”

This parameter setting the data type control telegram received. Options:

1bit (on-off control or PWM)

1byte (Continuous)

Under the “1bit “control, the valve control is similar to the normal switch control: the room temperature controller controls the output of the valve through the switch

command. When the thermostat fails and the output does not receive the control signal, the valve will automatically carry out the PWM action according to the valve

position set under the fault. The channel sets the PWM cycle time and is used for this purpose.

Under”1byte” control, the room thermostat sends control values between 0 and 255 (corresponding to 0%.100%). This process is also called “continuous-action control “.

the valve is closed at 0%, and at 100% it is fully open, at 0%...100% intermediate value, the channel controls the output through the pulse duty cycle adjustment.

Note: under the heating actuator function, each time the telegram of continuous regulation is received, the channel recalculates the duty cycle of the pulse

according to the new control value, the time is up, and the action is carried out.

• Parameter “Reply the status for continuous control”

This parameter is visible when previous parameter is selected as “1byte(Continuous)”,for setting reply the status for continuous control. Options:

No reply

Yes,0%=0, otherwise “1”(1 bit)

Yes,0%=1, otherwise “0”(1 bit)

Yes, continuous control value(1 byte)

• Parameter “Reply the status for contact”

Options:

No reply

Yes,0=contact close; 1=contact open

Yes,1=contact close; 0=contact open

When select ”No reply”, communication object will not reply the status for contact;

When select “0=contact close ; 1=contact open”, when the value of communication object “status of contact”is “0” indicates contact close, when “1” indicates contact

open;

When select“1=contact close; 0=contact open”has the contrary meaning.

Note: After programmed or system reset, if switch status is assure, object “Status of contact” will send status telegram to the bus: if it is not assure, status

telegram will not be sent.

Parameter “Function for monitoring is”

This parameter setting whether to enable monitoring function. Options:

Disable

Enable

The following parameters are visible when parameter “Function for monitoring is” is selected as “Enable”:

• Parameter “Cyclic monitoring of thermostat [0..65535]s”

This parameter sets the time that the device monitors the control telegram from the thermostat.

Normally the control telegram of the room thermostat is sent to the device at certain time intervals, and if one or more adjacent control telegrams are not received, the

device’s function can indicate a communication or a thermostat fault in the room. If the controller’s control message is not received within the time set by this parameter,

the device automatically starts fault mode. The fault mode ends when the device receives the control telegram again. Every time a control telegram is received, the

monitoring time will be reset. Option:

0..65535

Note: If this function is activated, the room thermostat must periodically send a control telegram out. The monitoring time shall be greater than the interval

when the controller sends the control telegram .
