{{msg.payload}} part was 30 by default. It needs an integer, I guess. How can I fix this issue?
Description says this:
How and where should I set the topic to "control", and a "number" as payload?
remove 30 in countdown
use change node to set msg.topic as control and msg.payload as the number. Keep 30 as is
msg.number is not needed.
Set topic as below
It is not counting now, it is stuck at 0.
Under the node, I see 3600, when I choose 60 min and click on the switch, but the text stays at 0.
Export the flow and post it here.

you need to select all nodes while exporting
Sorry about that.

Thanks a lot! One last thing. I need a function to convert it into min:sec type. How can I do that?
Use a function node and follow this
Thanks a lot! I'll look into that. I don't know how I am going to get those values to the payload.
Also, I failed at the buzzer part. I wrote a function like this:
var cdtimer = msg.payload;
var buzz = 0;
if(cdtimer === 0)
{
buzz = 1;
msg.payload = buzz;
return msg.payload;
}
msg.payload = buzz;
return msg.payload;
It says that the node is trying to send message of type number. How can I fix this? I am trying to make the buzzer beep for 10 times, each beep lasting a second, then a second delay after each beep.
Edit: I did the formatting part. Now, only the buzzer part is left. I am using GPIO13 for it. Digital Output. Initial state is 0.
I had to come back to the remaining time formatting issue as it started bugging me. If you're running Node-RED 1.1.x, you can use a change node to set/change msg.payload to the following JSONata expression:
$moment(
$moment()
.add($$.payload, 'seconds')
.diff($moment())
).utc().format('HH:mm:ss')
Example flow demonstrating this that uses node-red-contrib-countdown-timer:

I don't know if this is the simplest way using JSONata but at least it seems to work. 
This fixed the issue for 1+ hours. But now, I see 23:59:59 in off state. How can I make it 00:00:00, or just empty?
I noticed something similar. The countdown node allows setting an on and off payload that are sent from the first output. Experiment sending a value from that output to your dashboard?
I didn't understand what you suggest.
