1) Probably not if the timer looks identical and is approximately the same weight, and not a lightweight knock-off product.
Which doesn't make sense why a chinese company would knock off a timer that doesn't sell in giant quantities, and there are so many other similar timers on the market from Utilitec, Woods, GE, Tork, etc.

2) The Intermatic brand FD and FF series timers have phillips-head screw terminals for connecting wire, and wire enters on the side.

3) All spring-wound timers are rated heavy-duty for 1HP at 120Volt and 2 HP at 240Volt. Set times are approximate. Timer has 1 year limited warranty against defects in manufacture and will last many years as long as amp-rating is not overloaded.

4) Call Intermatic customer service

1) Yes a spring-wound timer will work.
Woods 59717, Intermatic FD60, etc
There are other models depending on length of time, and color of timer

http://waterheatertimer.org/Countdown-timer-horsepower-ratings.html

2) How to wire to 24 volts
24 volt circuit has 2 wires going to load.
Cut one of the wires and then connect cut wire to timer.

3) Buy Woods 59717 or Intermatic FD60 timers at Amazon.com in home improvement.
Both products have 1 year warranty, and both are strong companies.
Spring-wound timers last many years, and set-times are approximate.

This timer appears to be Leviton LTB60
http://waterheatertimer.org/Countdown-timer-horsepower-ratings.html

Timer has 1 year limited warranty, evidently from manufacturer.
If timer is making humming sound, then it is defective, possibly receiving undervoltage on the line, or wiring installed incorrectly.

Switch noisy timer with one of the other timers, and see if problem follows the timer, or is related to the specific location.
Otherwise replace with LTB60 from Amazon for $24.
Or buy Intermatic Ei200 timer, or replace non-electronic with spring-wound timer such as 60-minute Intermatic FD60, or 30-minute FD30, etc.

PSW15 is typical spring-wound timer with metal cover and 15 minute time range.
Paragon is no longer making this timer.

However there are many spring-wound replacement timers that come with metal or plastic cover, and various time ranges.

For example Intermatic FF15 with metal cover:

If you want 30 minute timer range, order FF30

Woods 59713 with metal cover:
http://www.smarthome.com/56013/Woods-59713-15-Minute-Spring-Wound-Timer-Gray-Plate/p.aspx
If you want 30 minute time range, order 59716

You need "15 minute countdown timer" for a bath fan.

2) Easiest to wire is mechanical spring type countdown timer, FD series.

4) Amazon sells reliable 15 minute Intermatic electronic countdown:

6) Spring wound timers connect easily to same wires that come off old fan switch.
Old switch has 2 insulated wires, connect them to either terminal on spring wound timer.

7) Electronic timers are wired differently:

Some really old timers, the knob attaches with a tiny screw located on the knob.

A) GE 15069 image at Amazon

15069 manual
http://www.jascoproducts.com/support/manual-downloads/applications/DocumentLibraryManager/upload/In-Wall-15069-Manual-eng.pdf

Manual shows GE 15069 countdown timer is rated up to 1/2 horsepower
Whole house fan is likely 3/4 horsepower >> check nameplate on fan motor.

B) work around:
Hook timer up to a contactor/relay.
Timer turns on 120 volt, 7 watt contactor coil.
Contactor turns on fan motor

C) List below shows countdown timers with horsepower rating:

Intermatic spring wound countdown timers are rated for 2 horsepower

Woods spring-wound countdown timer says bath/ ceiling fans, but doesn't give horsepower
http://waterheatertimer.org/pdf/Wood-59700-series--spring-wound.pdf
http://waterheatertimer.org/Woods-timers-and-manuals.html#countdown

Woods push-button countdown is 1/4 horsepower
http://www.amazon.com/Woods-59014-Decora-12-8-4-2-12-Hour/dp/B002C54GH4

Lutron MA-T51 countdown timer specifically says it cannot be used for motors, which says the electronics inside each device is Load specific

Pass and Seymour RT1 countdown does not show rating for horsepower, so this timer will probably not work for fan motor
http://www.homedepot.com/Electrical/h_d1/N-5yc1vZ1xg8Zarcd/

Wattstopper RT50 at Grainger shows 1/6 horsepower rating

It's broken.
I have a FF series countdown timer on a water heater circuit that's been used for past 4 years.
The FF and FD series timers are heavy duty, spring-wound countdown timers.
I expect 10 years is a good lifespan.
You can buy a new spring-wound countdown timer at Home Depot or Lowes, but new ones are lighter weight than the good ol' Intermatic.

Grainger sells the FF60 (60 minute, metal cover)
http://www.grainger.com/Grainger/INTERMATIC-Spring-Wound-Timer-6X546?Pid=search
Grainger shows the FD60 (60 minute, plastic)
http://www.grainger.com/Grainger/INTERMATIC-Spring-Wound-Timer-1XC27?Pid=search

Grainger Intermatic timers shows a lot of FF and FD timer choices:
http://www.grainger.com/Grainger/intermatic/ecatalog/N-1z0r56r
There are several pages of Intermatic timers:
FF5minute thru FF12hour
FD15minute thru FD60minute

Most of these wil just pull off, but some has a small set screw on the knob.
