RC 2000 Lowest Setpoint

I'm glad I found y'all. I have an old installation where I recently swapped out an RC80 with an RC2000. It's a second home situation where in the Winter the setpoints are low (45-50). It's a hot water base board system. The zone that has the RC2000 seems to be hovering around 51 and not going any lower. This could be due to many "new" factors in the house (insulation, new heating system), but I wanted to ask if this tstat will allow a setpoint of 45 say? The RC80 did. Perhaps it's due to the added logic (Anticipator, EEC, Min On/Off)?
 
The default lower limit is 51. Try going into the Installation settings and finding the Cool/Heat Limits - see how low it'll let you go.
 
Thanks for responding. That would make sense then and I'm going there this weekend and will check out the Heat Limit.
 
From the install manual.....

Cool/Heat Limit
These items are used to limit the desired temperature settings in cool and heat mode. The desired cool setting can never be set below the “Cool Setpoint Min” setting and the desired heat setting can never be set above the “Heat Setpoint Max” setting. The default setting for cool is 51°F. The default setting for heat is 91°F.

...so if I'm in Heat Mode the "Cool Setpoint Min" is the as low as my setpoint can go?
