How to Use Glow Worm Mastermind Timer in new Property All aspects of plumbing questions and answers, help, tips and information

[newhomeowner]

I have moved house and the new house has an old heating system for central heating and hot water. The timer panel says Glow Worm Master Mind on it. Anyone know how to use it? I can get the central heating to work but don't know how to set the hot water timer.
Thanks
