Kay, Cymbidiums need outside in summer /autumn & cool unheated room winter
i.e. porch,conservatory .To put it simple.
I do have the same problem as you though,I have a greenhouse for my orchids
55-60 f min & heated house & conservatory.

Day temps should be 75 to 85 f or more. night temperatures in the late
summer to Autumn (August to October) must be 50 to 60 degrees F to
initiate
flower spikes. Optimum temperatures in winter are 45 to 55 degrees F at
night and 65 to 75 degrees F during the day. When in bud, temperatures
must
be as constant as possible, between 55 and 75 degrees F or the buds may
drop!Hope this helps and hasn't put you off growing these fascinating &
addictive plants known as orchids,they are tougher & easier to grow
than
most people think .

Easier, do you say! ;-)

Day temps of 75 to 85 or more means I'll have to put it back in the
greenhouse for the summer, winter temperatures are unachievable -
greenhouse is 40-45 deg, house is over 60.

I'm sticking to Phalaenopsis, which seem happy on the east facing toilet
window.
