## Preventing stuck valves by forcing actuation

When left in place for too long, radiator valves might seize. Following rules will force actuation every week in order to prevent this.
A time of `600` seconds should be long enough for slow actuators to open fully, adjust yours as needed.
If using above `windowstop` code, skip `Rules#Timer=1` as you already have it set.

```
ON Event#forceactuate DO Backlog EnableOutputSet 0; Power 1; RuleTimer1 600 ENDON
ON Rules#Timer=1 DO EnableOutputSet 1 ENDON
ON Clock#Timer=1 DO Event forceactuate ENDON
```
```
Timers 1
Timer1 {"Enable":1,"Mode":0,"Time":"08:00","Window":0,"Days":"0100000","Repeat":1,"Output":1,"Action":3}
```

If you have a button on your controller, consider using it to trigger the `forceactuate` event.
This allows you to request instant heating when feeling cold. Add to your rule:
```
ON Button1#State DO Event forceactuate ENDON
```
