The ST799 time control programmer can be used as a replacement programmer on gravity, primary or fully pumped systems. The ST799 offers a flexible 7 day programme. The front panel of the programmer will fit to the same backplate. Programming the timing sequence is straightforward, using the top slider switch and [+] and [-] buttons. Please note it is recommended that, in order to comply with Part L1 Building Regulations central heating systems should be upgraded to fully pumped with a fully independent programmer e.g. ST9400C.
