Set a timer with a reminder to close the window instead
Or even better, turn off the radiator valve when the window is opened, I do this with this rule:

rule "Generic Windows Changed"
when
    Member of HeatingWindows changed or
    Member of Radiators changed
then
    if (previousState == NULL || triggeringItem.state == UNDEF) return;
    val String room = triggeringItem.name.split("_").get(0)
    val GroupItem window = Windows.members.filter[ i | i.name.contains(room) ].head as GroupItem
    val SwitchItem radiator = Radiators.members.filter [ i | i.name.contains(room) ].head as SwitchItem
    if (radiator.state == ON) {
        if (window.state == OPEN) {
            sendCommand(room + "_RadiatorValve", "OFF")
            postUpdate(room + "_ThermostatMode", "off")
        }
    }
    if (radiator.state == OFF) {
        if (window.state == CLOSED) {
            val offset = House_HeatingOffset.getStateAs(QuantityType).doubleValue
            val target = (Targets.members.filter[ i | i.name.contains(room) ].head.state as QuantityType<Number>).doubleValue
            val ambient = (AmbientTemps.members.filter[ i | i.name.contains(room) ].head.state as QuantityType<Number>).doubleValue
            if (ambient <= (target - (offset / 2))) {
                sendCommand(room + "_RadiatorValve", "ON")
                postUpdate(room + "_ThermostatMode", "heat")
            }
        }
    }
end
