NEW YORK (Frankfurt: HX6.F - news) , March 5 (Reuters) - U.S. stocks were set for a flat open on Wednesday after two days of sharp swings as investors shrugged off a softer than expected reading on the labor market and ahead of two reports on the services sector.

* U.S. private employers added 139,000 jobs in February, shy of economists' expectations calling for a gain of 160,000 jobs, while January's number was revised downward by 48,000 to 127,000 jobs.

* Following the most serious confrontation between Russia and the West over influence in Ukraine and control of Crimea, a global investing flight to safety on Monday reversed sharply on Tuesday. Markets were calmer on Wednesday, but volatility was expected given the fluid situation in Ukraine.

* The S&P 500 closed at a record high Tuesday ahead of the first face-to-face talks between Russia and the United States on averting the risk of war in the Crimean peninsula.

* Other data expected on Wednesday includes measures of services sector growth for February from Markit, at 8:58 a.m. (1358 GMT), and from ISM, at 10:00 a.m. EST (Other OTC: ECPCY - news) (1500 GMT).

* S&P 500 e-mini futures rose 0.5 point and were about even with fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 7 points and Nasdaq 100 futures added 3.5 points.

* Honeywell International (NYSE: HON - news) rose 0.5 percent to $95.11 in light premarket trade after the diversified manufacturer of aerospace parts and climate control and security systems set a target of increasing overall company sales to more than $50 billion by 2018 as it spends $10 billion on acquisitions and continues to expand profit margins.

* Canadian Solar Inc (NasdaqGS: CSIQ - news) slumped 6 percent to $41.05 before the opening bell. The solar panel maker warned of a drop in current-quarter revenue as about $100 million in sales were deferred after a severe winter.
