Help with some schedule logic please

Hi Guys
Just got my C touch and I am looking at the logic required for my heating.
The C touch needs to take care of the schedules and in effect take the place of a normal central heating clock.
Therefore there will be three outputs, Boiler on, Zone 1 and Zone 2. There must also be the option for 4 on and offs during a period and 2 periods (weekdays and weekends) This gives 48 Time paramenters that need to be adjusted on the screen.
Does the logic below look ok to you guys.

WK = week
WE = weekend
B= Boiler
Z1= Zone 1
Z2 - Zone 2

IF TIME > WK B ON 1 AND < WK B OFF 1 OR
TIME > WK B ON 2 AND < WK B OFF 2 OR
TIME > WK B ON 3 AND < WK B OFF 3 OR
TIME > WK B ON 4 AND < WK B OFF 4 OR
TIME > WE B ON 1 AND < WK B OFF 1 OR
TIME > WE B ON 2 AND < WK B OFF 2 OR
TIME > WE B ON 3 AND < WK B OFF 3 OR
TIME > WE B ON 4 AND < WK B OFF 4 OR
ZONE 1 ON OR
ZONE 2 ON THEN
BEGIN
BOILER ON = TRUE
ELSE BOILER ON = FALSE
END

IF TIME > WK Z1 ON 1 AND < WK Z1 OFF 1 OR
TIME > WK Z1 ON 2 AND < WK Z1 OFF 2 OR
TIME > WK Z1 ON 3 AND < WK Z1 OFF 3 OR
TIME > WK Z1 ON 4 AND < WK Z1 OFF 4 OR
TIME > WE Z1 ON 1 AND < WK Z1 OFF 1 OR
TIME > WE Z1 ON 2 AND < WK Z1 OFF 2 OR
TIME > WE Z1 ON 3 AND < WK Z1 OFF 3 OR
TIME > WE Z1 ON 4 AND < WK Z1 OFF 4 THEN
BEGIN
ZONE 1 ON = TRUE
ELSE ZONE 1 ON = FALSE
END

IF TIME > WK Z1 ON 1 AND < WK Z1 OFF 1 OR
TIME > WK Z1 ON 2 AND < WK Z1 OFF 2 OR
TIME > WK Z1 ON 3 AND < WK Z1 OFF 3 OR
TIME > WK Z1 ON 4 AND < WK Z1 OFF 4 OR
TIME > WE Z1 ON 1 AND < WK Z1 OFF 1 OR
TIME > WE Z1 ON 2 AND < WK Z1 OFF 2 OR
TIME > WE Z1 ON 3 AND < WK Z1 OFF 3 OR
TIME > WE Z1 ON 4 AND < WK Z1 OFF 4 THEN
BEGIN
ZONE 2 ON = TRUE
ELSE ZONE 2 ON = FALSE
END


Thanks
