Inquiry (采购产品): Replacement Thermostats I currently have a White-Rodgers # 1E35-910 thermostat which I would like to replace with a recommended # 1F90-371 Thermostat. However my zone valve motors are White-Rodgers Models 1311 & 1361. I am aware of compatability issues between these valve motors and some digital programmable thermostats, is that also the case here? If so what would you recommend. And if not how can I purchase a 1F90-371, your site only lists installers who generally refuse to sell to the public unless they do the installation. I do not wish to pay someone big bucks to loosen and tighten a few screws on what is basicaly a small job. **** Hidden Message ***** Robert Cofer NY 12590 USA Company: Homeowner Phone: 914-584-3492 E-mail: scubadiver@paradisereef.com **** Hidden Message ***** scubadiver@paradisereef.com
