M1 Gold for heating only, rules?

Hello if I wanted to use my M1 Gold system only for heat control and nothing else what would be the best way to setup the rules? I have 8 rooms but lets say 3 for an example rooms with M1ZTS’s installed on Zones 1-3 and I have 3 hot water circulation pumps connected to a M1XOVR output 31,32,33 going to each room.

What do you think the best approach for this would be? I currently setup 6 different rules to check every 45 seconds. 2 for each room:

WHENEVER EVERY 45 SECONDS
AND Zn1ACTUAL TEMPATURE IS LESS THAN 70 DEG F
THEN TURN Out 31 ON

WHENEVER EVERY 45 SECONDS
AND Zn1 ACTUAL TEMPATURE IS GREATER THAN 70 DEG F
THEN TURN Out 31 OFF

This seems to work but wondering if there is a better way to do this. Could the system possibly miss a check since all the rules are firing at the same time? Should the temps be 70 and 71 instead of both 70 if that is the target temperature?

Would it be better to set this up checking if the zone is secure or not instead of firing every 45 seconds? If so then would it just rely on if the system is armed or not?

Thank you in advance for any help, this project fell into my lap so im slowly learning as much as I can.
 
This is how I would approach this:

Whenever Zn1Actual Temperature becomes less than 70 Deg
Then turn out 31 ON

Whenever Zn1Actual Temperature becomes greater than 73 Degrees
Then turn out 31 OFF

I would be better to have a "deadband" difference of 1, 2 or maybe up to 5 degrees between ON and OFF settings. That will prevent the pump output from "Chattering" in case the temperature is setting right on 70 and there is a little noise there which will cause it to turn on of off quickly and repeatedly.

The rules run whether the system is armed or not. But you could revise a rule so that it will only run when armed or disarmed (with an AND statement).
