how do i operate towerstat rsp central heating thermostat controller

I don't have any info in the RSP verison, However I did find the following programming instructions: Start with a full reset in case it has locked up: Press the inset button between the down temp and 'P' buttons Set the time using the M (Min), H (Hour) and D (Day) buttons Press 'P' to get into programming mode, one press gives program (setting) 1, 2 presses program 2 etc, you have 6 programs. M. H & D set day & time, up & down sets the programmed temp. R resets back to run mode. P1 Weekday Morning On (temp ) P2 Weekday Morning Off (temp ) P3 Weekday Evening On (temp ) P4 Weekday Evening Off (temp ) P5 Weekend Day On (temp ) P6 Weekend Day Off (temp) I hope this helps you.
