The ST699 time control programmer can be used as a replacement programmer on gravity primary or fully pumped systems. The ST699 has a proven easy to use design. 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. For more information on this product please visit the European Product Catalogue.
