[From the Merriam Webster dictionary] thermostat: an automatic device for regulating temperature A senses the room temperature and controls the HVAC system according to a schedule established by the homeowner. This type of thermostat allows different temperature settings to automatically regulate the HVAC system at different preset times.
A programmable thermostat works fine with a heat pump. Just remember that a heat pump does not heat as fast as a furnace because of the lower BTU ratings so do not set the thermostat as far back as you normally would. Also make sure to buy a thermostat that has heat pump terminals.
A programmable timer usually just means a timer that can be programmed to go off at any time.
PLA is programmable logic array while PAL is Programmable Array Logic. PLA is a kind of programmable logic device used to implement combinational logic circuit. It has Programmable AND Gate linked with Programmable OR Gate. PAL is an combinational PLD that was developed to overcome certain disadvantage of PLA. PLA shows longer delay due to additional fusible links which results from using two programmable array and increase circuit complexity. Thus, PAL is used which is less complex and fast to implement. PAL consists of programmable AND linked with fixed OR.
PLA: both AND and OR gates are programmable. PAL: AND gates are programmable whereas OR gates are fixed.
Programmable logic ASICs is a classification of ASICs are programmed by blowing fuses in a device to alter the logic function.
The thermostat is non-programmable. So you cannot program it.
An electric programmable thermostat will save on electric bills by not running durring the evening.

There are several different places where one can purchase a Honeywell programmable thermostat from. Some of these places include the official Honeywell website, Canadian Tire, and Amazon.
An electronic programmable thermostat has a printed circuit board on which is mounted a chip one or more relays LCD display terminal strip sometimes a backup battery
A few companies that offer programmable thermostats are DTE Energy and Energy Star. A programmable thermostat can save a household hundreds of dollars every year.
A Honeywell 7 Day Programmable Thermostat is approximately $119.00 at home improvement stores such as Lowes or Home Depot. The advantages of a programmable thermostat far outweigh the disadvantage of the price. These even allow you to access them with your smartphone to change the temperature on demand!
The Honeywell EConnect RedLINK wireless thermostat control system is a good programmable Internet thermostat that will work with baseboard heaters. It allows you to control up to eight separate baseboards.
I think if you are using a radiant heating system like warm board that can respond quickly to changes in temperature then a programmable thermostat makes sense. However if you are using concrete slab radiant heat, which takes a long time to heat up and cool down a programmable thermostat will be less efficient than leaving it at one set temperature.
